Cutter unit 14 is at centering guiding piece 26 place joint continuity band 6 slidably.

More specifically, the centering guiding piece 26 preferably carried by bracket 19 is at passage opening 27 joint continuity band 6, and the width of described passage opening 27 equals the width of continuous band 6 self.Thus, continuous band 6 can keep centering to locate relative to cutter 18.In fact the possible sideway movement carrying the continuous band 6 of feedway 5 is easy to the lateral translation of the correspondence causing bracket 19.In fact, by centering guiding piece 26 joint continuity band 6, horizontal thrust is delivered to cutter unit 14 by the cross motion due to continuous band 6.

Described guiding device 28 is accommodated in and includes in the described generation region " Z " of cutter unit 14.Guiding device 28 pairs of continuous strip linear elements 2 operate, to apply corresponding biasing force to continuous strip linear element 2, thus along these continuous strip linear elements 2 of the locus guiding mutually dispersed moved away from corresponding cutter 18.

More specifically, guiding device 28 comprises skew roller 29, and each skew roller 29 is suitable for preferably by having the operating surface 29a of protrusion profile with the relational operation contacted with in continuous strip linear element 2.

Preferably, each continuous strip linear element 2 produced by cutter unit 14 is provided with at least two skew rollers 29, the track that described at least two skew rollers 29 are dispersed along the longitudinal midline " L " from continuous band 6 is aimed at mutually.

Preferably, skew roller 29 is all freely rotatably supported along corresponding pivot center " X ", and described pivot center " X " tilts slightly relative to the direction perpendicular at the longitudinal extension part of the one section of continuous strip linear element 2 offseting self upstream of roller 29.Thus, continuous strip linear element 2 will produce the skew thrust expected in the mode against skew roller 29 by skew roller 29, and this skew thrust is suitable for making the continuous strip linear element 2 away from cutter 18 translation have the track dispersed; These tracks are relative to each other dispersed and/or are dispersed relative to continuous band 6.

More specifically, offset roller 29 and can be located so that each continuous strip linear element 2 has expediently: first to depart from from least one of the laying plane " P " of continuous band 6 after being cut by corresponding cutter 18; Second to depart from at least one, described second departs from and departs from described first contrary, and namely described second departs from the longitudinal extension direction transverse to continuous band 6.First departs from and departs from the component that can also depart from as single inclination with second and implement simultaneously.

The size of biasing force can be regulated by the control apparatus 30 relevant to guiding device 28.Thus, correctly stable track can be provided for the single continuous strip linear element 2 produced by cutting.

If necessary, biasing force can also be regulated in response to the possible cross motion of continuous band 6.These cross motions of continuous band 6 are produced by the multiple factor being difficult to predict or control, and these factors are such as present in band feedway 5 or other region of cutter unit 14 upstream; In fact, such sideway movement causes bracket 19 sideway movement, and causes the relative motion between cutter 18 and single skew roller 29, and result changes the track of continuous strip linear element 2 and is applied to the skew thrust of continuous strip linear element 2.The controllability of biasing force allows to compensate these changes, and recovers the dynamical equilibrium condition of the continuous strip linear element 2 of translation on each skew roller 29.

For this reason, each skew roller 29 can be supported by rod 31 expediently, and described excellent 31 are engaged rotationally by the substrate 32 carried by the supporting construction 23 of cutter unit 14.More specifically, when being activated by drive member 33, each excellent 31 can both rotate around correction axis " Y ", and described correction axis " Y " is perpendicular to the rotation axis " X " of roller self, and the above-mentioned generation region " Z " that described drive member is positioned at continuous strip linear element 2 is outside.

For each skew roller 29, drive member 33 comprises at least one first screwing element 34 (such as ring nut), at least one first screwing element 34 described engages rotationally with the supporting construction 23 of cutter unit 14, and is positioned at outside relative to the above-mentioned generation region " Z " including cutter unit 14.

The drive link 35 relevant to the rod 31 to corresponding relative to the first screwing element 34 of supporting construction 23 axial restraint operates.Such as, drive link 35 comprises actuating arm 36, described actuating arm 36 is such as operatively tied to lever 38 by ball-and-socket type joint 37, and described lever 38 by the engaged at end of holder 39 with corresponding rod 31, thus radially stretches out relative to above-mentioned correction axis " Y ".

First screwing element 34 operatively engages the second screwing element 40, and the screw thread that described second screwing element 40 is such as carried by actuating arm 36 represents.

Thus, by driving the first screwing element 34 to rotate, corresponding skew roller 29 can be adjusted around the locality revising axis " Y ", to finely tune the biasing force acted on continuous strip linear element 2 produced by this skew roller 29.

After the trajectory stability of the continuous strip linear element 2 with time gap quite frequently, translation being left to cutter 18 carries out visual spatial attention, manually can regulate biasing force.In fact, after detecting that track exists possible irregularity, operator's M/C first screwing element 34, to revise the one or more track in continuous strip linear element 2.

Operate in time for the ease of operator, when the position of the divergent section of at least one continuous strip linear element 2 exceeds predetermined tolerance threshold value, signaling device 41 can be used to give notice signal, such as acoustic signal and/or visual signal.

Such as, such signaling device 41 can comprise sensor component 42, such as the sensor component of optics, machinery or other type, and it detects the position of each divergent section in the continuous strip linear element 2 produced in region " Z ".

In preferably programmable electronic control unit 43, store the theoretical principle position of the divergent section in each continuous strip linear element 2.The comparator 44 be connected with electronic control unit 43 compares the position detected by sensor component 42 and the theoretical principle position of presetting.

When difference between the position and theoretical principle position of divergent section exceeds predetermined tolerance threshold value, can be given notice signal by signaling device 41.

In a preferred embodiment, after described electronic control unit 43 output signal, at least one actuator (not shown) is by automatically regulating corresponding skew roller 39 to act on each first screwing element 34 around the orientation of above-mentioned correction axis " Y ".

Cutting implemented by each cutter 18 between the reinforcement cord 3 of two vicinities of continuous band 6, to make each continuous strip linear element 2 have the reinforcement cord 3 of predetermined quantity.

But, there will be following situation: due to during manufacturing at a high speed continuous band 6 relative to the not controlled motion of cutter 18, one in the reinforcement cord 3 that one or more cuttings in cutter 18 are adjacent, and system has new equilibrium conditions, wherein not all continuous strip linear element 2 is all formed with correct width and/or is formed with the reinforcement cord 3 of predetermined quantity.

In order to eliminate the problems referred to above, cutter unit 14 can also be connected with thruster 45, the relative positioning that described thruster 45 can be revised between continuous band 6 and cutter 18 by making cutter unit 14 cross motion when needed during the translation of continuous band-shaped element 2.More specifically, from generation region " Z " external drive thruster 45, to make cutter 18 relative to skew roller 29 cross motion.

Preferably, thruster 45 comprises the actuator arm 46 carried by bar 47, and described bar 47 preferably has round section, and can pass through the supporting construction 23 of bracket 19 by axial motion rotationally.The control dial 48 that bar 47 carries allows actuator arm 46 is moved between dormant state and serviceability, and in described dormant state, actuator arm 46 and bracket 19 are thrown off, and at described serviceability, actuator arm 46 engages with bracket 19.For this reason, actuator arm 46 such as can be provided with forked end portions 49, and the crawl carried by centering guiding piece 26 handle 50 of dashing forward can be inserted in described forked end portions 49 removedly.

Under the normal operating condition of manufacturing line 1, actuator arm 46 remains in the dormant state that actuator arm 46 is thrown off with bracket 19.When needs carry out correction operation, operator can operate control dial 48, to make actuator arm 46 engage with bracket 19, and less impact or thrust is passed to bracket self, thus makes cutter 18 cross motion rapidly.

Due to the counteraction caused at the continuous strip linear element 2 with translation under the state that engages of skew roller 29, these cross motions cause continuous band 6 to move relative to cutter 18, thus recover the tram of continuous band 6 relative to cutter 18.
