Patent attributes
A device for making it possible to apply to a pack, moved along a conveyor, a handle (n) of nominal length L situated at the end of a tape. The tape includes a succession of handles (n+i), each handle comprising two adhesive ends and a central part. The device includes a feeder to move the tape as far as a rotary application arm having a length which is equal to the nominal length L. This arm is able to deposit one adhesive end of the handle n on one face of the pack and then the second end of the handle n on a second face of the pack. The device further includes an optical cell for detecting an offset in the position of a handle n+i, an actuator for elongating the length of the rotary arm beyond the nominal length L, making it possible during a rotation of this arm to draw a portion of tape having a length greater than the nominal length, and a control unit.
