Abstract

1320112 Cutting apparatus K BRAND 1 Feb 1972 [24 Feb 1971] 4738/72 Heading B4B [Also in Division B8] Apparatus for cutting sheet material comprises a cutting-out press 1 having an elongated table 19 for supporting the sheet material during cutting, material supplying means 12 movable by a first driving means 21, 22, 23 relative to the cutting-out press in the longitudinal direction of the table, second driving means 27, 28, 29 for feeding the material towards the cutting- out press over guiding rollers 37, 38, and a carrier 13 for supporting rolls 48 of the sheet material, the carrier being coupled to the material supplying means. The material supplying means 12 includes a base frame 14 mounted on rollers 15 for movement on a track or floor 16 and a pair of columns 18 connected at their upper ends to the table 19 for movement therewith ; the table being provided with rollers for movement over the bed 7 of the machine. The frame is moved by means of a motor 21 rotating a sprocket 22 in engagement with a chain connected to the base frame 14. A member 36 is pivotally mounted on the base frame and, when in the horizontal position shown in Fig. 1, forms a platform on which the operator stands. A pair of feed rollers 27, 29 are rotatably mounted on the upper ends of the columns 18, the roller 29 being carried by pivoted arms 31 movable by screws 34 in order to vary the nip between the rollers; the roller 27 may be rotated by a handle 28 on by power means. The rolls 48 of materials are mounted in roller bearings (50), Fig. 4 (not shown), carried by arms 46 which are mounted on a frame structure 44, 45; the stub shafts (49) of the rolls are retained in the bearings by a pivoted lever (51) secured by a wing nut-and-screw device (53). The frame is mounted on rollers 43 and connected to the base frame 14 by latches 41 so that upon actuation of the motor 21 the material supplying means 12 and roll carrier 13 move together with the table. In a modification, Fig. 5 (not shown), the roll carrier (73) is mounted at the rear of the machine and connected by latches (75) with the material supply means (72) by an extension 74 thereof which passes under the cutting out press. Chain-andsprocket drives (83, 84) are provided at the front and rear of the machine and actuated by a single motor (82). In a further embodiment, Fig. 6 (not shown), the material supply device (101), roll carrier (108) and work-table are maintained stationary, the cutting-out press itself being mounted on rollers (106) and arranged to be moved relative to the latter parts.
