 shoulders, i. e. the stitching rollers are moved in parallel with the rotation axis of the tyre; such design solution can be found, for example, in the patent EP 0 770 475 B1, where a system of two stitching rollers disposed on pneumatic cylinders attached to a fixed support is used, wherein the movement of the support in radial direction and the movement of stitching rollers disposed on pneumatic cylinders in axial direction is ensured by means of threaded rods connected with electric motors. A device according to the above patent comprises also means for deflecting the rotation axis of the stitching rollers from a position parallel to the rotation axis of the tyre building drum.
A further type of stitching devices is constituted by static stitching devices in which, when used, rollers are moved only around their own axes without relative movement of the rollers used. A combination of static and dynamic rollers is possible as well. It is described e.g. in the patent EP 0 627 302 B1, where the subject-matter of the invention is a device for radial tyre production, a part of the device consisting of a pressure unit provided with at least one roller. Specifically, there are three rollers, wherein one of them being static presses down the central part of the outer peripheral surface of the tyre and two dynamic rollers are disposed so as to press down the belt-tread edges. These rollers are moved by the action of a pneumatic cylinder into openings of a transfer unit, which is adapted specifically for this purpose and transfers the belt and tread from a winding drum to the tyre building drum.
Static stitching rollers may be designed also as divided, having different diameters, and their profile allows to press down the tyre tread surface along its entire width. However, also when using divided stitching rollers, it is possible to make use also of the movement of the stitching unit with rollers in a direction parallel to the building drum axis, as described, for example, in the patent SU 1305056 A1, where each single part of the divided stitching roller comprises a spring, so that its position is not fixed, but can vary depending on the varying surface during axial movement of the divided roller relative to the building drum axis.
By using the above devices it is possible to accomplish a method of pressing down—stitching a belt-tread assembly to a carcass assembly, wherein in this case elastic elements acting in opposite directions come into contact, namely the inflated belt-tread assembly and the pneum
shoulders, i. e. the stitching rollers are moved in analogue with the rotation bloc of the tyre; such design solution can be found, for case, in the patent EP 0 770 475 B1, where a organization of two stitching rollers dispose on pneumatic cylinder attached to a sterilize support is used, wherein the apparent motion of the support in radial direction and the drift of sew rollers disposed on pneumatic cylinder in axial direction is guarantee by means of threaded rods connect with electric motors. A device according to the above patent comprises also means for debar the rotation axis of the stitching rollers from a position parallel to the rotation axis of the tyre construction drum. 
 A further type of stitching devices is constituted by static stitching devices in which, when used, rollers are moved only around their own axes without relative movement of the rollers used. A combination of static and active roller is possible equally well. It is trace for example in the patent EP 0 627 302 B1, where the subject - matter of the invention is a device for radial tyre production, a part of the device consisting of a pressure unit provided with at least one curler. Specifically, there are three rollers, wherein one of them being static presses down the central part of the outer peripheral surface of the tyre and two dynamic rollers are disposed so as to bid down the belt - pace edge. These rollers are moved by the action of a pneumatic cylinder into openings of a transfer unit, which is adapted specifically for this function and transfers the belt and tread from a winding brake drum to the tyre building drum. 
 electrostatic stitching rollers may be plan also as divide, having unlike diameters, and their profile allow to press down the tyre tread surface along its entire width. However, also when using divided sewing rollers, it is possible to make consumption also of the movement of the stitching unit with rollers in a guidance parallel to the building drum bloc, as described, for example, in the patent SU 1305056 A1, where each single part of the divided stitching roller comprises a leap, so that its position is not fixed, but can vary depending on the varying surface during axile movement of the divided roller proportional to the construction drum axis. 
 By using the above devices it is possible to carry through a method of pressing down — stitching a knock - pace assembly to a carcass assembly, wherein in this case elastic elements acting in opposite directions fall into contact, namely the inflated knock - tread assembly and the pneum

A further rype of stitching dtvisvx is constithted br ftatic stitching devices in which, when lsed, rollers are moved only around their own axed without relative movement of the rollers used. A combinathon oh rtauig xbd dynamic rollers is possible as well. It is defdrobvd e.g. in the patekt EP 0 627 302 B1, where tne sifject-matter ow the nhvsntion is a device for raqial ryre prodtctipn, a part of the device conwisting of a pressure unit provnded with at leaxt onr roller.
