Definitions
- the invention relates to a receiving means for receiving sheet material for use in a winding machine according to the preamble of claim 1. Furthermore, the invention relates to a method for performing an automated roll change for a winding machine, a device for performing an automated roll change and a film production device.
- films are produced as continuous material and are wound up on receiving means (eg sleeves) in winding machines. After a desired length of film has been wound on the receiving means, a roll change is performed. For this purpose, the film must be severed and wound on a new receiving means. It is known from the prior art to prepare the receiving means with an adhesive and then set down on a film web, which is lifted from the contact roller. A direct placement of the receiving means on the contact roller is avoided, since due to the adhesion of the surface of the receiving means on the contact roller surface tear off parts of the receiving means and pollute the contact roller.
- a disadvantage of the known solutions for a roll change is that the lifting of the film web from the contact roller is more complicated and complex to implement. Furthermore, it is often not possible to wrap the film on the receiving means in an envelope-free manner. Furthermore, tearing of the film web may occur due to the adhesion of the receiving means to the film. In a direct placement of the receiving means on the contact roller (without lifting the film web previously) solve due to the adhesion by the adhesive parts of the receiving means and soil the contact roller. Next, a manual gluing of the receiving means is necessary, which is a complex operation and therefore associated with high costs and speed losses.
