The invention describes a sleeve for sliding onto and removing from a winding shaft, which comprises a one-piece workpiece defining a cylinder, which workpiece comprises two edge regions each having an edge, the edge regions overlapping one another, the sleeve having a first diameter in a relaxed state, the sleeve in a clamped state having a second diameter which is different from the first diameter, the sleeve in the clamped state experiencing an elastic deformation as compared to the relaxed state.

Sleeve, winding device, and method for repeated, successive winding of webs to form reels of material

The invention relates to a method for successively winding a film web onto a plurality of spools, wherein the film web is wound to form a first spool, and a tube and/or winding shaft for forming a subsequent second spool and the film web are moved closer to one another and/or are brought into contact with one another upstream of the first spool. The film web is cut, and thus an end of the film web is produced, with end is wound onto the first spool, and a new start of the file web is produced, which is wound onto the second tube. In order to cut the film web, the film web is cut partially in the transverse direction, at least one cut edge and at least one uncut region remaining in the transverse direction, the uncut region being subsequently torn off or cut off.

Method and device for successively winding a film web, and film roll

A separating device () for separating a tubular flat material () having an actual tube width (), comprising at least one longitudinal separating unit () for removing a first edge region () and a second edge region () of the flat material () is provided. In addition, a separating method () for separating a tubular flat material and to a system () having a separating device () is provided.

Separation device for separating a tubular flat material, system and separating method

The present invention relates to a device () for automatically cutting a material web () with a longitudinal cutting device () using a material web () in a longitudinal direction (L) separable in at least a partial web () and/or at least a remaining web (), a discharging device () for automatically discharging the produced remaining web (), a transverse cutting device () downstream of a longitudinal cutting device () for cutting the remaining web () transversely to the longitudinal direction (L).

Apparatus for automatically cutting and discharging a web of material, and associated method

The present invention relates to a Suction nozzle () for a suction device () for conveyance of cut waste strips () of a film web () comprising a nozzle duct () with a nozzle inlet () for suctioning the waste strips () and with a nozzle outlet () for introducing the waste strips () into the suction duct (), wherein the nozzle duct () comprises an inlet portion () adjacent to the nozzle inlet () and an outlet portion () adjacent to the nozzle outlet () and between the outlet portion () and the inlet portion () an at least one rotation portion () is assembled, whose flow cross section () is at least partially twisted over the run of the rotation portion ().
