ABSTRACT:
A hooper device for joining together a pair of overlapping steel bands includes a band tensioning device for stretching the bands with a punching and stamping tool including a lower tool section arranged on a base plate of the device toward which an upper tool section is moved. The upper tool section is arranged in a tool support which is structured in the form of a rocker and the tool support is connected by means of a reset device with a driving mechanism. The driving mechanism includes a manual lever having a driving cam with a radial cam which acts upon a pressure roller arranged at the tool support. The rocker construction of the tool support provides a simple, weight saving, operationally safe arrangement for the hooper device.
