Disclosed herein, a tire tread cutting apparatus for cutting a length of a tire tread is described. The tire tread cutting apparatus includes a track having a first track end and a second track end downstream of the first track end. The track includes a plurality of rollers positioned between the first track end and the second track end. The plurality of rollers is configured to facilitate the tire tread along the track. A tire hub is positioned downstream of and adjacent to the second track end. The tire hub is configured to receive a tire casing. The tire casing defines a tire casing circumference along an outer surface of the tire casing. A tread dispenser is positioned upstream of the track and configured to dispense tire tread. The tread dispenser includes a drive roller configured to drive tire tread downstream toward the second track end.

A method and an apparatus for correcting a feeding distance of a strip or cutting, involves feeding the strip over the feeding distance in a feeding direction towards a cutting line that extends at an oblique cutting angle to the feeding direction; detecting a lateral position of a first longitudinal edge of the strip in a lateral direction perpendicular to the feeding direction; wherein, when the detected lateral position is offset over an offset distance in the lateral direction with respect to a reference position for the first longitudinal edge at the measuring line, and adjusting the feeding distance with a correction distance that is related to the offset distance in a ratio that is defined by the cutting angle.

Method for controlling the feed of semifinished products in a tyre building process, said method comprising: feeding a semifinished product (10) into a building station (30) adapted to build, through said semifinished product (10), a structural component of a tyre; performing, in an acquisition zone (AZ), a verification to verify the presence of at least one defect of said semifinished product (10); generating a notification signal (NS) as a function of said verification; activating, as a function of said notification signal (NS), a discard device (60), configured for discarding at least one portion of said semifinished product (10) comprising said at least one defect.

Disclosed is a creel including a plurality of creel bobbins, a plurality of guiding tubes located at the lower end of the creel and a plurality of guiding tubes located at the upper end of the creel, wherein each guiding tube is arranged for receiving a wire from an individual creel bobbin, wherein the lower half of the creel bobbins are arranged to feed their wires to the guiding tubes at the upper end of the creel, while the upper half of the creel bobbins are arranged to feed their wires to the guiding tubes at the lower end of the creel.

The invention relates to an automated device to transfer and thread a bearing band (3) on a fixed reel (2) from a removable reel (1), said reels (1,2) being joined and integral to corresponding shafts (4,5), wherein said device comprises a folding arm (6) adapted to perform a translational movement, which in turn comprises a hook (7) and a carriage (8) configured to move the arm (6) horizontally between both reels (1,2), and wherein the device further comprises a tensioning roller (10) adapted to move vertically through an intermediate column (11), such that it allows the first bearing band (3) to be transferred between reels (1,2) automatically in order to finally wind a second bearing band (12) with the first bearing band (3) onto the removable reel (1) automatically and simultaneously.

A separation device (1) intended to separate a profiled element (2) from a conveying surface (3) which conveys the profiled element (2) in a longitudinal direction (L0) comprises a detachment roller (10) which is mounted so as to be able to rotate on a support (11) about a detachment axis (X10), and which is intended to be interposed, in an engagement configuration (C1), between the profiled element (2) and the conveying surface (3) to cause the profiled element (2) to become detached from the conveying surface (3).

Disclosed is a transfer wheel, a transfer device and a method for transferring a strip, in particular a run-flat reinforcement strip or a sidewall strip, to a tire building drum, wherein the transfer wheel defines a retaining area that is divided into a first end section for retaining the leading end, a second end section for retaining the trailing end and a main section for supporting the strip body. The transfer wheel has a first mounting member that defines first mounting positions for receiving a first group of retaining segments at the first end section, wherein the first group of retaining segments includes first body retaining segments for retaining the strip body and a first end retaining segment for retaining the leading end, wherein the first mounting member is arranged for interchangeably receiving one first body retaining segment or the first end retaining segment in each first mounting position.

A method and an apparatus for correcting a feeding distance of a strip or cutting, involves feeding the strip over the feeding distance in a feeding direction towards a cutting line that extends at an oblique cutting angle to the feeding direction; detecting a lateral position of a first longitudinal edge of the strip in a lateral direction perpendicular to the feeding direction; wherein, when the detected lateral position is offset over an offset distance in the lateral direction with respect to a reference position for the first longitudinal edge at the measuring line, and adjusting the feeding distance with a correction distance that is related to the offset distance in a ratio that is defined by the cutting angle.

A topping sheet forming method includes: a feeding and division step of feeding a textile original fabric, obtained by weaving longitudinally aligned tire cords into a cord fabric by use of weft yams, and cutting off the weft yarns in predetermined widthwise positions to divide the textile original fabric into a plurality of narrow textile original fabrics; a calender step of topping, with unvulcanized rubber, at least one surface of one narrow textile original fabric out of the divided narrow textile original fabrics; and a wind-up step of winding up the other narrow textile original fabrics out of the divided narrow textile original fabrics.

The device comprises at least one module for stitching the tread and a means for moving the module vertically and horizontally. The stitching module comprises a frame which is provided with a fixed stitching assembly, equipped with spikes, and at least one mobile stitching assembly. The at least one mobile stitching assembly comprises at least one stitching plate provided at the base of same with at least one planar horizontal contact surface, from which at least two spikes protrude. The plate is arranged in a vertical guide space provided in the frame such that the spikes protrude downwards and such that it is free to move vertically in this space over a limited travel path. The device also includes a vertical movement device for moving the plate from the top downwards in this guide space and a device for locking the altitude position of the plate in this space.
