DEVICE TO JOIN EDGES OF WORKPIECES OF SHEET-LIKE ELASTIC MATERIALS Russian patent published in 1995 - IPC

FIELD: production of prefabricated articles of elastic materials. SUBSTANCE: plates of the device are of box-like shape with bearing surfaces of curvilinear shape corresponding to the shape of edges of workpieces being joint. Bearing surfaces of the plates are located at an angle to each other. This angle corresponds to the preset angle in edge joint of workpieces in the article. The plates are enable to be installed with displacement in horizontal plane. The device is equipped with intermediate plate installed vertically between the plates. The plate has two faces crossed at an angle specified by edge joints in its upper end. Profile of faces corresponds to curvilinear profile of bearing surfaces of plates. There is perforation on both sides of faces ends. Vertical thrust member and power cylinder connected to it through a rod is used as aligning mechanism for curvilinear edges of workpieces. Thrust member has folded out step and aligning surfaces in its lower part. EFFECT: easier assembling. 5 dwg
