Press force is applied by two press elements hinged togethr via angle levers (8,9) which press off press element (5) and connect in tension to element (6). The angle lever (8) is joined to lever (9) for tension transfer. The press elements (5,6) face one another and their ends associate with knee levers (10), being joined to this (10) by outside joint (12,13). The levers (8,9) differ in length so the shorter knee lever (8) applies force through element (14) excentric to the outside joint specified. The longer lever (9) of the one or both knee joints (10) is joined to an additional press element (15,16). |
