<p>1474925 Cutting apparatus CHAMBON Ltd 29 Oct 1974 [30 Oct 1973] 46725/74 Heading B4B A device for cutting a web of material, e.g. paper, longitudinally, comprises a frame 9a, 9b, in which two shafts 1, 2 provided with blades 7, 8 are rotatably mounted, a control means 15, 15a 16 for displacing one of the shafts both axially and radially for engaging or disengaging the blades, a support 10 in which both shafts can be locked against axial movement, and means 27, 28, 29 for displacing the support, together with the shafts, in the axial direction. The shafts 1, 2 are rotatably mounted on respective spindles 3, 4 and rotated via gears 5, 6. The spindle 3 is slidably journalled in the frame member 9a and the support 10, the journal being eccentric to the axis 1a of the spindle. A cam member 15a is pivotally mounted on one journal such that, by movement of a handle 15, the shaft is allowed to move axially under the action of a spring washer 8, to thereby disengage the blades; by rotating the handle, the shaft is moved radially due to the eccentric journals so that a web may be inserted between the two blades. The degree of rotational movement of the handle may be limited by a pin 22 engaging the end of a slot 23 in the support 10. The pin is mounted in a plate 20 which may angularly set on the spindle journal by a screw 21 the location of the pin and slot may be reversed and an indicator pointer-end-scale provided. The support 10 is slidably guided on pins 25 and may be adjusted by a screw device 27 in order to move both mating blades across the width of the web.</p> |
