- The-invention relates to a conveying table for the transverse feeding of sheets of paper, paste board, card board or sheet metal and other sheetlik'e material, equipped with oblique driving rollers, directing ruler and press bodies'arranged in front of the ruler.

The invention consists in that the sheets or the like are deflected from the direction in which they enter already at a greater distance from the directing ruler of the transverse conveying table and of the press bodies coordinated to the same, i. e. balls,.rollers, brush wheels or the like, that the sheets are moved towards the directing ruler of the transverse conveying table in a larger curve, and that, in preserving their movement, they go over into the transverse direction.

- It'is known to provide a transverse conveying table'between the paper working machines arranged at an angle the one to the other, for instance between two folding mechanisms standing at right angles the one to the other, said transverse conveying table consisting of driven oblique driving rollers and of an adjustable directing ruler. On these transverse conveying .tables with oblique rollers a row of press bodies such as balls, rollers, brush wheels or the like is arranged directly in front of the directing ruler and cooperates with the driven oblique rollers, that is loads on the same or is adjusted. relative to the same with pressing-on pressure. This row of press bodies serves to brake the sheet'in i'ront of the directing ruler-for instance the" sheet delivered at great speed from the ilrst folding mechanism and, after it has been discharged from the delivering. conveying rollers of: this folding mechanism, said sheet being without September 6,1940, serial No. 355,658 In Germany October 1, 1938 with oblique rollegs, the sheets, sheet parts, fold-.-

ed pieces or the like delivered, for-instance, from the first folding mmhanism are flung towards the directing ruler and braked by the press bodies arranged directly in front of the ruler, the sheets passing under this ruler. The sheets come, on the directing ruler, first into a position of rest, but are, after a short moment and influenced by the action of the driven oblique. driving rollers and press bodies, iurther'conveyed in the transverse direction. A loss of time is due to the fact that the sheets or the like must first is flung against this directing ruler without guidsince-in order to avoid rising and upsetting of the front edgeof the sheet on the directing ruler. These press bodies serve further for accelerating the sheet conveying in the transverse conveying direction. Finally it is P ssible .that byfthe press bodies a distance can be formed on the transverse conveying table with oblique rollers between the successive sheets on the same in such cases when at the same time several sheets the one at the side of the other, for instance 7 sheets cut into two parts, folded pieces or the be moved in the admission direction up to the directing ruler, come into a position of rest on this rulerand must be further moved from this position of rest, this loss 'of time reducing the efliciencyohthe machine.

It may further be mentioned that it is also known to drive the conveying rollers of this table at different speed, for instance the front group of these conveying rollers at greater revolving speed, for forming a distance between the sheets or the like successively fed on a transverse conveying table with oblique rollers. It is also known to arrange with this object in view the conveying rollers of the transverse conveying table, which rollers revolve at similar revolving speed, in a different angular position. the one to the other.

According to the invention, the sheets, sheet .parts, folded pieces or the like are deflected from their admission position at a greater dise tance from'the directing ruler, moved towards the directing ruler in a greater curve and, preserving their movement, go over into the transverse direction, whereby an increase of efficiency is attained. The danger that the front edge of the sheet rises and is upset on the directing ruler in this feeding of the sheets against the directing" ruler in a curve is further absolutely excluded.

An embodiment of the invention is illustrated by way of example in the accompanying drawings which show twofolding mechanisms arranged at right angles the one to the other and destined for cross-folding. I

Fig. 1 shows a folding machine with the transverse conveying table in top plan view, 8. 2, is a side elevation partly in section,

Figs. 8 to 6- are diagrammatic top plan views illustrating the simultaneous feeding of several sheets the one at the side of the other.

The sheets to be treated are fed in the direction oithe arrow A on a feeding table I consistbodies exerting diiierent effects upon the i ndividual sheets or the like. r

In these known transverse. conveying tables ing, for instance, of positively driven oblique rollers 2 and-lateral directing means, namely of v the press bodies tiballs), directing ruler 4, and a folding mechanism 5 of known type containing one or several .folding pockets 6. A cutting device I, adjllstable in lateral direction and removable, is arranged behind the folding mechanism 5. Conveying rollers 8 are provided at the outlet end of the foldingmechanism 5, by which rollers the sheetsare delivered on to a transverse conveying table 9 consisting of positively driven oblique rollers H1. The transverse conveying table 8 with oblique rollers III is provided with a directing ruler l2 adjustable on a bar It according to the form of the sheet. A row of press bodies such as balls I3 is mounted in front of the directing ruler l2. Instead of balls rollers, brush wheels or the like maybe used. The press bodies 13 load on the oblique rollers III or are adjusted to press against the same. All this is known.

In connection with the directing ruler I2 a sheet metal plate H is mounted roof-like above the oblique rollers III, the front edge of this plate being bent upwards to ensure the insertion of the incoming sheets, as shown in Figs. 1 and 2. Several small size sheet metal plates may also be provided, as shown in Fig. 6. 1

According to the invention one or several rows of preferably exchangeable press bodies, such as balls l5, co-operating with the oblique rollers III directed position.

If in the preceding description it has been stated that for obtaining the running on curves C and D, independent the one on the other, for the two arriving sheet parts, the press bodies IS in the first row destined for the left hand sheet part a are removed, the same proceeding can be carried out if on the sheet part a a less great number of balls l5 act or such balls of a lower weight act, that is the magnitude of the pressures and/or the number of the press bodies is adiustable or variable.

are arranged in addition to the row of-press bodies l3 arranged in front of the directing ruler l2, so that the sheet arriving on the transverse conveying table is positively deflected from the admission direction A, by the press bodies l5 for changing the direction of movement and cooperating with the oblique rollers Ill, already at a greater distance from the directing ruler l2 and the row of press bodies I3 coordinated to this directing ruler, so that further the sheet is conveyed in a larger curve (C, D) against the directing ruler l2 and, preserving its movement, is

transferred into the transverse direction B. The

sheet moves then along the directing ruler l2 into the next following folding mechanism It and is held in the directed position by the press bodies I3. The sheet is cross-folded in the folding mechanism It. A cutting device I'I adjustable in lateral direction and removable is arranged behind the folding mechanism IS. All positively driven elements are driven from a shaft I8 through the intermediary of intermediate gears.

Two additional rows of press bodies ii are arranged in the form of construction shown by way of example. If from the folding mechanism 5 whole sheets get on to the transverse conveying table in the direction of movement A. balls I! are placed into all or almost all holes l5 according to the .quality of the sheet to be used. The halls of the first row may exert a different pressure from those of the second row.

If the sheets folded in the folding mechanism 5 are cut by the cutting device I, that is if two sheet parts or folded pieces a, b, are fed at the same time to the transverse conveying table the one at the side of the other and in the admission direction A, as shown in Fig. 3, the balls in the first row of press bodies l5, against which, as

- shown on the drawing, the left hand part a of It is evident that also more than two sheet parts can be treated or conveyed; in this instance it is merely necessary to provide a corresponding greater numberof rows of press bodies and to increase the number of press bodies and to insert the press bodies in a suitable arrangement.

If from the first folding mechanism 5 sheets folded in very narrow high-form are brought on to the transverse conveying table, these sheets are prevented from tilting and assuming oblique position on the transverseconveying table according to the .invention in that the sheets are held in several zones at different points by the press bodies, so that wrong folding in such narrow high-formed sheets is avoided by this several times secured sheet holding.

I claim:

1. A conveying table for sheets of paper, paste board, card board or sheet metal and for other sheet-like material horizontally arranged between two treating devices such as folding mechanisms standing the one at anangle to the other and equipped with positively driven oblique driving rollers for conveying the sheets, an adjustable directing ruler for directing the sheets to be conveyed, and press bodies arranged directly in front of the, directing ruler and loading on the oblique driving rollers, comprising in addition to the row of press bodies in front of the adjustable directing ruler, a plurality of further rows of exchangeable press bodies arranged at a greater distance from thedirecting rulerso that thesheets coming from the first treating device and-moving on to the conveying table aredeflected from this conveying direction and moved in a larger curve towards the directing ruler and remaining in movement change into the transverse direction.

2. A conveying table as specified in claim 1, in

ruler, a plurality of further rows of exchangeable press bodies are provided at a greater distance from the directing ruler, the magnitude of the shown in Fig. 4. Whilst the right hand sheet part b moves sidewards, i. e. already in transverse direction, the left sheet part a first continues to move in the admission direction A and comes under the influence of the balls only in the second row of press bodies l5, as shown in Fig. 5. At this point also the right hand sheet part b, which has, however, moved away from pressures exerted by the press bodies being adjustable so thatwhen several sheets are simultaneously conveyed on the conveying table the one at the side of the other the running-on curves 0f said sheets are altered the one independently on the other.
