Apparatus for the edges of thermoplastic webs |
| abstract |
The edge knurling of a thermoplastic web must often be carried out at elevated pressure in order to ensure a sufficient knurling depth even after the web has been wound and unwound different times. The prior heating of the web margins permits knurling to be carried out at lower pressures but may adversely influence the crystallinity of a film and also requires an increased amount of energy. |
