US 5,158,000 A · Two-shaft method for slicing a cylindrical elastic body into rings and its apparatus

Abstract

This disclosure relates to a method for slicing a cylindrical elastic body, for example, a slab or broad belt prior to being cut into belts or rings of a certain width, by a two-shaft system, and its apparatus. The apparatus includes a) a drive shaft, of which the top end thereof can be released from its support, of which the root end thereof is connected to its drive unit, the drive shaft having a radially projecting part at the root end; b) a freely rotatable shaft extending in parallel with and at a constant distance from the drive shaft in a horizontal plane, of which the top end can be released from it support and can be tilted in vertical direction, and c) a cutting unit which has a cutter positioned perpendicular to the axial direction of the drive shaft, and which can move towards the drive shaft and can travel in the axial direction of the drive shaft. With the use of the above-mentioned apparatus, a cylindrical elastic body can be reliably and stably biased to one end of the two shafts supporting the elastic body, and slicing into rings of a desired width can be accomplished with high precision.

Dependent claims

A two-shaft apparatus for slicing a cylindrical elastic body into rings, said apparatus comprising

a drive shaft and a drive unit, said drive shaft having a top end thereof and a root end thereof which is connected to said drive unit, said drive shaft having a radially projecting part at said root end, said drive unit being reversible whereby said drive shaft may be rotated in a regular direction or in a reverse direction,
a freely rotatable shaft spaced from said drive shaft having a root end which is pivotably mounted and having a top end which can be tilted in a direction which is transverse of said plane, said top end being tiltable in both directions from said neutral plane, and
a cutting unit which has a cutter positioned perpendicular to the axial direction of said drive shaft, which is movable towards said drive shaft and is adjustable in the axial direction of said drive shaft, and further including a pair of sensors positioned adjacent one of said shafts, said sensors being spaced apart a distance which is substantially the same as the width of said elastic body, said sensors being responsive to one edge of said elastic body for determining movement of said elastic body.
