Abstract

1,261,175. Angular bending. HAMMERLE A.G. 3 Feb., 1970 [18 Feb., 1969], No. 5179/70. Heading B3E. A work-table for a press-brake includes a work-table panel 5, a support element 7 therefor extending the length of the work-table panel and mounted in a member 8 for vertical displacement therein and defining therewith a chamber 9 for receiving oil on which the element will rest. A bending tool 6 is supported on the panel 5 and the high pressure oil in the chamber 9 prevents distortion of the panel when downward pressure is applied to the tool.
