1,246,367. Cutting-out presses. E. MOHRBACH. 31 July, 1969 [31 July, 1968], No. 38456/69. Heading B4B. A cutting-out press, e.g. for stamping insole blanks from sheet or web material comprises a resiliently mounted table 4 for supporting the material below a punch 3 and having an aperture through which a knife blade 5 projects so that, upon actuation of the press, the blank falls by gravity through the aperture. The table 4 is formed from three parts 13, 14, 15 which are supported on springs 16, 20, the parts 13, 14, together with the knives 5, being mounted on plates 17; the plates are adjustably mounted in guides 18 secured to the frame of the press. The table part 15 is mounted on the springs 20 supported on the frame and adapted to cooperate with a material clamping piston 30 carried by the punch 3. The punch is provided with a wear plate 21, e.g. of plastics material mounted on a slide plate 35 which is linearly movable in guides 44, Fig. 3, by means of an hydraulic ram 34; the plate 35 is attached to a second plate 36 which is rotatable via guides 45, Fig. 6, around the punch 3 by means of a second ram 37. The material is intermittently fed over the table by means of a gripper 22, Fig. 7, which is reciprocated by means of a hollow piston-rod 23 of an hydraulic actuator and rotated via a rod 42 connected to a further actuator (33, Fig. 5); the gripper mechanism is adjustably mounted on a slide in order to suit different width material. The cut-out blanks fall through the knives 5 on to conveyers 9 which, via a deflector plate 10, Fig. 1, causes the blanks to fall on to a stepped portion (53, Fig. 9) of an inclined plate (51); the stepped portion is connected via a part (54) to an extension support plate (55). A gripping member (57) is pivoted on one end of a lever (58) and arranged to pass through a slot formed in the plate (51); the other end of the lever is pivoted on a bracket 59. By suitable actuation of rams (60), (61), the member 57 transfers the blanks one at a time from the step 53 to the support plate 55.
