Abstract
In a method for processing a cushioning material strand, which is produced by a cushioning conversion machine from a web-shaped stock material (e.g. a roll or a leporello stack, for example of paper), the cushioning material strand is wound around a winding center into a cushioning material winding and is compressed during winding into the cushioning material winding.
Claims21
A method for processing a cushioning material strand produced by a cushioning conversion machine from a web-shaped stock material, the method comprising:
- winding, using a winding device, the cushioning material strand around a winding center into a cushioning material winding;
- guiding, using at least one guide movably mounted relative to the winding device, the cushioning material strand, wherein the guiding including following a height profile of a circumferential course of an outer layer of the cushioning material winding;
- and
- compressing the cushioning material strand, at the outer layer of the cushioning material winding and during winding of the cushioning material strand, into the cushioning material winding.
A device for processing a cushioning material strand produced by a cushioning conversion machine from a web-shaped stock material into a cushioning material winding, the device comprising:
- a winding device configured to wind the cushioning material strand around a winding center;
- a deformation device configured to compress the cushioning material strand at an outer layer of the cushioning material winding;
- and
- at least one guide that is movably mounted relative to the winding device and configured to follow a height profile of a circumferential course of the outer layer.
A device for processing a cushioning material strand produced by a cushioning conversion machine from a web-shaped stock material into a cushioning material winding, the device comprising:
- a winding device configured to wind the cushioning material strand around a winding center;
- a deformation device configured to compress the cushioning material strand at an outer layer of the cushioning material winding;
- and
- a squeezing device configured to apply a squeezing force to the cushioning material strand at the outer layer of the cushioning material winding in a radial direction (R) of the cushioning material winding, the squeezing device being arranged radially opposite the winding center and/or at least one deflector of the winding device, wherein the squeezing device comprises a lever arm configured to be brought into tangential contact with the outer layer of the cushioning material winding.
