Device for separating, delivering and depositing blanks |
摘要 |
The invention relates to a device for separating, delivering, and depositing material blanks, for use in the textile industry or the like which improves heat transfer to the gripping surface in a device in which the heating device is arranged in such a way that it is protected from external forces. The device comprises a heatable gripping plate, which has a gripping surface and an expansion chamber adjacent thereto, in which a refrigerant is able to expand and thus cool the gripping plate to below the freezing point so that a material blank will freeze onto said gripping surface. The side of the chamber opposite the gripping surface is closed by a nonmetallic intermediate plate whose surfaces are essentially parallel to said gripping surface and can be coated with metal, and which intermediate plate has a noncoated surface with an electrical heating resistor arranged therein and a metal-coated surface that is in metallic connection with a plurality of webs that form a bridge for heat transfer from the intermediate plate to the gripping surface.
