Method and device for processing a teat rubber during production

摘要

During the production of teat rubbers, in particular of teat rubbers containing a high percentage of silicone, pressure is applied when the teat rubber preforms are removed, the radial expansion of teat rubber areas being appropriately limited to a maximum value. Hence, the removal can be executed automatically and at a comparatively high temperature without irreversible damage being caused to the material. The removal process can be supported by an appropriate contact surface whose contour corresponds, at least partially, to the outer contour of the preform. Furthermore, an appropriate removal device is provided.

1. Device for removing a preform of a teat rubber which has a head region with a contour and a tube region and is applied at least partially to an element determining the inner shape of the teat rubber, said device comprising:
a removal unit with a shaped contact face adapted to the contour of the head region which is to be brought at least partially into contact with the head region of the preform, a fluid introduction means which is embodied for introducing a pressurized fluid into the tube region, and limiting means for limiting the radial expansion of the tube region on introduction of the fluid, wherein the shaped contact face is modelled on the contour of the preform and in that a traction mechanism is provided for exerting a tensile force on the preform via the shaped contact face in the direction of the longitudinal axis of the preform.
