Abstract

In conventional profile shears with a fixed or movable cutter bar arranged on a frame, the frame has to absorb high shearing forces and ensure accurate guidance of a member carrying the cutter bar, which leads to heavy and expensive constructions. The invention achieves the object of creating relatively light-weight, compact and easy-to-maintain profile shears of high cutting capacity by arranging a slide (2) carrying the displaceable cutter bar (3) and by arranging the fixed cutter bar (5) in a housing (1), the slide and housing having entry and exit openings (10, 11, 13, 14) for the profiled material (9) which are in alignment with the shearing opening (8) of the cutter bars. Such a housing (1) common to both cutter bars can reliably absorb the shearing and pressure forces of the cutter bars with a simple and compact type of construction. Especially advantageous is a loose arrangement of the cutter bars in recesses of the slide or of the housing, in which case upwardly pointing openings of these recesses permit easy exchange of the cutter bars. <IMAGE>
