Abstract
A stuffer box crimping device has a pair of feed pressure rolls and a stuffer box arranged downstream thereof. The stuffer box is laterally delimited by side panels extending up to a nip of the pressure rolls. Pressure plates are supported in the side panels at the level of the pressure roll nip, the pressure plates being in contact with end faces of the rolls with an adjustable pressure. In order to prevent the heating up of the pressure plates during rotation of the pressure rolls, the pressure plates are designed to be cooled during operation. For this purpose, a unit is provided for supplying a cooling liquid against the pressure plate; the liquid being continuously discharged again from the unit after contacting the pressure plate.
