Abstract
The invention relates to a method for producing a dry film (3), wherein a dry powder mixture is processed into the dry film (3) by a rolling device comprising a first roller (2a) and a second roller (2b). The first roller (2a) has a higher circumferential rotational speed than the second roller (2b), and the dry film (3) is placed on the first roller (2a).
Claims14
A method for producing a dry film, in which
- a dry powder mixture is processed into the dry film by a rolling device having a first roll and a second roll, wherein
- the first roll has a higher rotational peripheral speed than the second roll and the dry film is supported on the first roll,
- wherein a ratio of the rotational peripheral speed of the first roll to the rotational peripheral speed of the second roll of 10:5 to 10:1 is maintained, and
- wherein the dry powder mixture contains polytetrafluoroethylene.
