Abstract

PURPOSE:To enhance an production efficiency as well as to reduce cost in processing by compactly arranging processes such as stamping elastic materials, caulking contacts, stamping fitting materials and the like, and thereby making continuous processing possible as a production line. CONSTITUTION:An elastic material W1 is forwarded by a quantitative feed device B at the left side, piercing and trimming being processed by a stamping device C, a rivet which is forwarded by a rivet supply device D, being inserted into a bored hole. Successively, a contact being inserted therein so as to be caulked, and is forwarded to the center section of a machine thereafter. In the second place, a fitting material W2 is forwarded from a quantitative feed device H at the right side, piercing, trimming, lancing and the like being processed by a stamping device J, and is cut off so as to be pushed forward to the center section of the machine wherein the elastic material W1 is cut off so as to be squeezed by the rivet integrally together with the fitting material W2. Thus, when processes are arranged into a production line, a production efficiency can thereby be enhanced, and cost can also be reduced.
