Abstract

Device for cutting and transferring a length of strip let off a continuous strip, comprising a first face and a second face to be laid on a rotary receiving surface and containing
a cutting means to separate the said length from the continuous strip along a cutting line, a telescopic conveyor belt, arranged in a longitudinal direction between the cutting means and the receiving surface, to receive the length of strip via the first face, a first half-anvil, upstream of the cutting line, and comprising holding means to grasp the strip via the first face, a transporter, having holding means to grasp the front edge or rear edge of the length of strip via the second face, the transporter able to move in the longitudinal direction. A second half-anvil is intended to collaborate with the first half-anvil during cutting, and positioned downstream of the cutting line and upstream of the telescopic conveyor belt, comprising holding means able to grasp the rear edge of the length of strip via the first face, and able to move in the longitudinal direction.

First claim

The invention claimed is:

1. A device for cutting and transferring a length of strip (T) let off a continuous strip (B), the length of strip (T) and the continuous strip (B) each comprising a first face (T 1 ) and a second face (T2) and intended to be laid on a rotary receiving surface on which the various components that make up a tire can be assembled, and the device comprising:
a cutter able to separate the said length of strip (T) from the continuous strip (B) along a cutting line (LC),
a telescopic conveyor belt, arranged in a longitudinal direction (Y′Y) between the cutter and the receiving surface, and intended to receive the length of strip (T) via the first face (T 1 ) of the length of strip (T),
a first half-anvil, arranged upstream of the cutting line (LC), and comprising a magnetic mechanism or a vacuum mechanism able to grasp the continuous strip (B) via the first face (T 1 ) of the continuous strip (B),
a transporter, having a magnetic mechanism or a vacuum mechanism able to grasp a front edge (T f ) or rear edge (T r ) of the length of strip (T) via the second face (T 2 ) of the length of strip, said transporter being translationally driven in the longitudinal direction (Y′Y), and
a second half-anvil adapted to collaborate with the first half-anvil during a cutting of the continuous strip (B) to define the length of strip (T), and positioned downstream of the cutting line (LC) and upstream of the telescopic conveyor belt, comprising a magnetic unit or a vacuum unit able to grasp the rear edge (T r ) of the length of strip via the first face (T 1 ) of the length of strip, and be translationally driven in the longitudinal direction (Y′Y) in sync with the transporter such that the rear edge (T r ) and the front edge (T f ) of the length of strip (T) are both grasped during movement of the length of strip (T) thereby allowing the length of strip (T) to not experience tension after the cutting as the transporter and second half-anvil and telescopic conveyor belt translate the length of strip (T) in the longitudinal direction (Y′Y), wherein the conveyor belt is arranged to translate the length of strip (T) on a bearing surface of the conveyor belt which extends from a first roller to a second roller, the device configured to cause the bearing surface to reduce in length by reducing a spacing between the first roller and the second roller during the translational driving of the second half-anvil.

2. The cutting and transfer device according to claim 1 , wherein the second half-anvil is able to move between a position in which the two half-anvils are in contact with one another, and a position in which the second half-anvil adjoins an upstream part of the telescopic conveyor belt when the telescopic conveyor belt is in a retracted position.

3. The cutting and transfer device according to claim 1 , wherein the cutter is a cutting blade that can be run substantially along a line of contact between the two half-anvils when the two half-anvils are in contact with one another.

4. The cutting and transfer device according to claim 1 , wherein the transporter is able to move in the longitudinal direction (Y′Y) between a first position situated substantially above the first half-anvil, and a position situated substantially above the receiving surface.

5. The cutting and transfer device according to claim 1 , wherein the half-anvils and transporter comprise electromagnetic or controlled-magnetization magnets.

6. The cutting and transfer device according to claim 1 , wherein a part of the telescopic belt that is intended to receive the continuous strip (B) or the length of strip (T) runs over a telescopic support table.

7. The cutting and transfer device according to claim 1 , wherein the transporter is able to move in a direction (ZZ′) perpendicular to a plane of the conveyor belt (OXY).
