The device for cooling an adhesive applied to a surface of bag bodies includes a transfer conveyor and a cooling conveyor. The transfer conveyor conveys the bag bodies at a transfer speed to the cooling conveyor, and the cooling conveyor conveys the bag bodies taken over from the transfer conveyor at a cooling conveyor speed. The transfer speed is higher than the cooling conveyor speed, which is why the bag bodies are arranged overlapping each other on the cooling conveyor. Due to this higher packing density, there is achieved a long dwell time of the bag bodies in the cooling conveyor at simultaneously a high flow-rate of bag bodies through the device.

Provided is an uneven roller of which a surface coming into contact with a medium is provided with a plurality of protrusions and recesses, the uneven roller including a shaft portion, a reference portion mounted on the shaft portion, a ring portion that is positioned closer to a side, to which a first direction along an axial direction of the shaft portion extends, than the reference portion is and that is mounted on the shaft portion, and a restriction portion that is positioned closer to the side, to which the first direction extends, than the ring portion is and that is mounted on the shaft portion to restrict movement of the ring portion in the first direction. The ring portion is composed of a plurality of uneven rings disposed along the axial direction, the uneven ring including a plurality of protrusion portions disposed along a circumferential direction.

A thermal roller (1) includes: a cylindrical body (2) extending along a longitudinal direction (X-X), the cylindrical body (2) including at least one inner tubular element (3) and at least one outer tubular element (4) that is concentrically arranged around the inner tubular element (3), the inner tubular element (3) includes an outer diameter d and the outer tubular element 4 includes an inner diameter D, being D>d; two hubs (6), each arranged at one end of the cylindrical body (2); at least one heat-exchange chamber (10) realized between the inner tubular element (3) and the outer tubular element (4). The roller includes: a coating layer (11) for the inner tubular element (3) made of plastics, and at least one helical channel (13) between the coating layer (11) and the outer tubular element (4). The helical channel (13) is realized at least partially in the coating layer (11).

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).

The present disclosure provides an adhesive applicator, an applicator system, and methods of applying an adhesive to a part. In one aspect, an applicator has an end effector that includes a roller wheel having a rotatable wheel and thermally-controlled tubes. The thermally-controlled tubes each define a chamber arranged to receive a heated working fluid. The end effector also includes leading rollers and lagging rollers that lead and lag the roller wheel, respectively. The leading and lagging rollers each define relief channels and are arranged to receive an adhesive substrate within their respective relief channels so as to pre-tension and align for placement of the adhesive substrate to a part to which the thermally-controlled tubes apply the adhesive substrate. The relief channels of the rollers along with controlled tensioning of the adhesive substrate and associated backing, maintain accurate placement of the adhesive substrate and removal of the backing during laydown.
