ABSTRACT:
Clamps or connector elements (13) are secured to the ends of a conveyor b (10) by a pressure applying clamping tool (11) which includes two clamping rails (1, 2) for clamping down the belt end prior to the attaching of the clamps. A single operating lever (9) is used for clamping the upper rail (1) down against the lower rail (2). For this purpose each end of the upper rail (1) is secured to a respective fixed point (2) by a tie rod (3) and a rocking lever (4). Each rocking lever (4) is connected to a spring biased pull rod (5) which is operatively connected to the single operating lever (9) through a toggle type connection.
