Title: Cutting Means
Inventor: KAISER HERBERT
IPC: B26D1/00
Filed: 1965-12-15
Abstract: 1,170,750. Cutting. AVON RUBBER CO. Ltd. 12 Dec., 1966 [15 Dec., 1965], No. 53229/65. Heading B4B. Apparatus for making skive cuts in a moving band of material, e.g. elastomeric material, to form lengths of tread and side-wall stock for use in the manufacture of pneumatic tyres, comprises a feed track 10 above which is a guide track 24 and below which is an inclined track 30 to receive the material with the formation of a loop which can enlarge from the position 36 to the position 38, the material being directed over a roller 18 which co-operates with an idler roller 22 and which may be driven, by means of a clutch mechanism and alternative drives 20, either at the same peripheral speed as that of the track 10 (i.e. line speed) or at twice line speed, past a position where a traversable disc skive cutter 40 co-operates with a transverse track 42, between a roller 46 co-operating with an idler roller 47 to an adjustable photo-sensitive mechanism shown by line 60. Braking means can be applied to the rollers 18, 46 and this braking means can be supplemented or replaced by inflatable braking means applied to the material. In operation, a cut having been made and the drive to the material having restarted and regained normal speed, the leading edge of the material reaches the photosensitive mechanism at which time an electric signal is produced which is used to cause the brake to be applied to the rollers 18, 46 and the drive to these rollersdisconnected. The cutter 40 is then caused to move along the track 42 to cut the stationary material. When the cutting stroke has been completed, the brake on roller 46 is released and a drive applied to this roller which accelerates the severed material to twice line speed. The severed material is received by the track 48, which is driven at a speed equal to or greater than line speed, and carried away to a collecting point. The brake on roller 18 is then released and this roller accleerated to twice line speed. This has the effect of decreasing the size of the loop from position 38 to position 36. At this time, the speed of the roller is reduced to line speed in readiness for the next cut.
