A dual roll laminating film cartridge refill for a reusable cartridge loadable in a laminating machine. The refill includes a first roll of continuous adhesive-coated translucent laminating film having a first axial end and a second axial end. The refill includes a second roll of continuous adhesive-coated translucent laminating film having a first axial end and a second axial end. A first connector couples the first axial ends of the first and second rolls at a predefined gap distance. A second connector is independent from and spaced from the first connector, the second connector coupling the second axial ends of the first and second rolls at the predefined gap distance. The first and second connectors are uniquely shaped and asymmetrical to provide a keyed interface to the reusable cartridge.

A conveying apparatus includes a conveyor which conveys a first sheet medium unwound from a roll body in a conveyance direction and which has first and second rollers to nip the first sheet medium at a nipping point; a pressing mechanism which is moved to a pressing position at which the first and second rollers are pressed against each other and a release position at which the first and second rollers are released from being pressed against each other; a detector which detects the first sheet medium located downstream of the nipping point; and a controller. The controller executes a first determining process of determining whether the first sheet medium is detected by the detector; a pressing process of moving the pressing mechanism from the release position to the pressing position; and a conveying process of causing the conveyor to convey the first sheet medium after the pressing process.

Application devices and methods are disclosed herein for applying adhesive elements and have a) a cassette unit comprising: a1) a guide arrangement having a supply roller and a receiving roller; a2) an issuing region having a dispensing edge; a3) a material strip having a number of adhesive elements. The devices and methods also have b) a base unit comprising: b1) a cassette receptacle; b2) a conveyor element having an adhesion-reduced surface; and b3) an application element.

Methods produce adhesive rolls having adhesive elements and comprise a) producing a dispenser material tape in a dispenser arrangement and comprising a multiplicity of adhesive elements, wherein the dispenser arrangement is configured to separate the adhesive elements from a web-shaped first release material in a dispensing region and to output them from the dispenser arrangement, b) producing receiving arrangements comprising a feed roller, a receiving roller, a guide arrangement, and a web-shaped second release material, c) guiding the dispenser material tape through the dispensing region, d) rolling the second release materials onto the receiving rollers, and e) outputting adhesive elements from the dispenser arrangement in the dispensing region and, in each case, transferring some of the output adhesive elements into the receiving regions.
