Abstract

1,225,696. Splitting. ARDOISIERES D'ANGERS S.A., and B. VIEMON. 26 March, 1968 [29 March, 1967], No. 14561/68. Heading B5E. Apparatus for cleaning laminated materials comprises a base 12 for supporting a plate of the material, suction devices 14 pivotally carried by piston and cylinder devices 15, 16, and a blade 30 adapted to provide a " trigger " cut when struck by a striking element 32. The suction device seach include a plate 18 having a peripheral flange 19, and flexible sealing material 20. When each device engages a surface of the plate, suction is applied and the device is moved away from the other device thus causing the plate to be split. A cut provided by the blade 30 assists the splitting action. During withdrawal the pistons may be rotated.
