Abstract
The invention relates to a winding machine for winding material webs, in particular foils or films, wherein the winding machine comprises a feeder system with a first belt feeder which, during the winding of the material web around a winding core in a first direction, wraps itself at least partially around the material web. The feeder system comprises a second belt feeder which is suitable for winding the material web in a second direction around the winding core.
Claims14
A winding machine with a feeder system for winding a material web of foil or film around a winding core, comprising:
- at least one circulating belt;
- a first belt feeder constructed and arranged to wrap the at least one circulating belt at least partially around the material web during a winding of the material web around the winding core in a first direction;
- and
- a second belt feeder constructed and arranged to wind the material web in a second direction around the winding core;
- wherein the first and the second belt feeders each comprise at least two levers, and wherein the levers have head ends and further include pressure elements arranged, respectively, in a region of the head ends of the levers.
