<p>937,118. Sawing. MOHOGS MEKANISKA VERKSTAD A.B. April 26, 1962 [May 9, 1961], No. 16036/62. Class 145. Wall board sheet is cut into strips by being pushed on to a roller table 2 and then fed into a number of saws 8 at one side of the table by feeding arms 20 on a carriage which is movable on rails 17 above the roller table. The sheet is held down on the roller table by roller means 4 which can be raised and lowered by a hydraulic or pneumatic cylinder 7 and in the vicinity of the saws is held down by roller means 13. The saws are driven by individual motors 9, 10 which are staggered to enable closer spacing of the saws to be obtained and each saw and motor is mounted on a carriage 28 adjustable by rack and pinion means 25, 26. The feeding arms 20 are adjustable along a girder 19 which can be raised and lowered on the carriage 14 by hydraulic or pneumatic cylinders 22. The carriage is driven by a motor 34 through chain, screw or toothed drive means. Where the sheets have already been sawn across before being moved on the roller table and it is desired that some of the past sheets should not be sawn further, a hydraulic or pneumatic cylinder 32 can be operated so that an arm 33 raises and pushes back one part sheet and creates a space into which the arms 20 can be lowered and cause feed of only some of the part sheets. The arms may be individually movable up and down.</p> |
