专利汇可以提供Sealing mechanism专利检索,专利查询,专利分析的服务。并且A power sealing mechanism for forming tension resisting joints in overlapping portions of bundle encircling and load retaining tensioned strapping and a seal blank has an air pressure operated cylinder-piston combination with a projecting piston rod connected to drive the joint forming mechanism mounted in a frame which in turn is mounted on the cylinder. The joint forming mechanism includes pairs of strapping and seal blank engaging jaws or bending dies pivotally mounted on the frame and at least one pair of rotatable deforming dies or punches rotatably mounted on the frame adjacent the jaws. The jaws are connected to be pivoted by the piston rod to have relative movement with respect to the deforming dies to cause the jaws to fold the seal blank closely about the overlapping strapping portions and to force the seal blank into engagement with the deforming dies to deform the sandwich of seal blank and the strapping portions into a tensioning resisting joint. The advancing piston rod carries a cam-like abutment to pivot a latch having first and second stops to a position where a spring pressed detent retains the latch at the end of the advancing and joint forming movement of the piston rod. The first stop would be engaged by the abutment upon too early withdrawal of the piston rod and thus prevent retraction of the joint forming dies unless the mechanism had been fully advanced. The second stop is engaged by the abutment near the end of the normal retraction of the piston rod after a complete joint forming operation so as to release the latch from its detent and to condition the mechamism for a subsequent joint forming operation.,下面是Sealing mechanism专利的具体信息内容。
