METHOD AND DOCTOR BLADE DEVICE FOR SPREADING A RESIN PASTE ONTO A CARRIER FILM, AND A RESIN SHEET INSTALLATION FOR PRODUCING RESIN SHEETS

摘要

A method for spreading a resin paste onto a carrier film includes feeding resin paste into a doctor blade unit having a doctor blade, using a feed device that includes a discharge opening through which the resin paste is fed from the feed device into the doctor blade unit, moving a carrier film on a base surface through a doctor blade gap that is formed between the doctor blade and the base surface, and spreading the resin paste onto the carrier film using the doctor blade. The discharge opening is positioned to be immersed into the resin paste that is in the doctor blade unit during operation of a doctor blade apparatus configured to perform the method. A resin mat installation for producing resin mats, particularly of SMC, includes at least one doctor blade apparatus as described above.
