A reversible stepping up mechanism for laminator

摘要

A reversible stepping up mechanism, the laminated in a hinge housing 80 is installed, a laminated film layer of the two support rollers 70 and 71 within this laminated according to the selection of the two housing 80 forward - or are moved backwards; characterized in that said reversible transfer mechanism is constructed from the following elements:a support 60, which is fixed on one side of the laminated of the two housing 80 is mounted, and with which a rollers roll of each step carrier roller 70 and 71 is supported;a lever 10, to which a first end, and on the opposite side has a second end, while from the middle part of this lever 10 between the first and second end a pivot shaft 11 which extends in an articulated manner, is connected with the support 60;a return spring which, between the second end of the lever 10 and the carrier 60 is fastened in such a way as to connect;a transmission gearing 50, which is fixedly on the rollers roll of a of the layer support rollers 70 and 71 is mounted outside of the support 60;..
