ABSTRACT:
A welding device for joining overlapping lengths of thermoplastic synthetic resin along the margins comprises two welding rollers (8) and (9). One of the welding rollers (9) is arranged at a lever (7) pivotably supporting at the base member (1) of the device, this lever being associated with a setting means (24). The pressure exerted by the setting means (24) on the lever (7) is detected by way of a pressure sensor (23) and fed to a control and/ or display unit. The device exhibits a wedge-shaped heated member (14) associated with the gap between the two welding rollers (8) and (9), this member being displaceably guided in the base member (1). The wedge-shaped heated member (14) is supported at a support, by way of which it is adjustable in the base member (1), via a pressure sensor (43) transmitting signals corresponding to the contact pressure of the wedge-shaped heated member (14) against the sheets of synthetic resin entering in between the welding rollers ( 8) and (9) to a control and/or display unit. Furthermore, a temperature probe is provided in the wedge-shaped heated member (14) which transmits its signals to a thermostat control. The energy supply to the welding device is effected by way of a portable accumulator via a cable (50).
