ABSTRACT:
A male die shaft is mounted in a longitudinally movable and rotary manner in a casing. A lever engages on the said shaft. By means of a motor driven cam, the lever is pivoted. By means of a coupling operable by a shift lever and by means of a gear, a tensioning wheel is motor-driven for tensioning the strip. The male die shaft is held in the raised position by a stop member operated by a stop lever. The shift lever and the stop lever are part of a control mechanism pivotably mounted on a shaft and which is operated by a feeler lever. As a result, the coupling and stop member are released and the male die shaft is lowered onto the strip ends. By means of a lever driven by a cam, male die shaft performs a pivoting movement transmitted via a tooth wheel drive to a shaft which imparts an oppositely directed pivotal movement onto a female die located in the base plate. The movement resulting from the pivoting movement of the strip portions produces the frictional heat necessary for welding purposes. By means of the common control mechanism and the non-couplable male die shaft a simple construction of the apparatus is obtained.
