Abstract

A mandrel assembly for manufacturing a tubular product includes a first plate (206), and a cantilever drive roller (202) extending from the first plate. At least one cantilever idler roller (204) also extends from the first plate, and means (218) is provided to rotate the drive roller whereby, in use, a strip may be engaged and advanced by the driver roller to the at least one idler roller and thereby wound about the rollers to form a tubular product.

Claims (31)

Claims
1 A mandrel assembly for manufacturing a tubular product, including:
a first plate;

a cantilever drive roller extending from the first plate;

at least one cantilever idler roller extending from the first plate; and means to rotate the drive roller whereby, in use, a strip may be engaged and advanced by the driver roller to the at least one idler roller and thereby wound about the rollers to form a tubular product.
2 A mandrel assembly according to claim 1, further including a motor for driving the drive roller.
3 A mandrel assembly according to claim 1 or 2, wherein the drive roller is located at the top dead centre of the mandrel.
4 A mandrel assembly according to any one of claims 1, 2 or 3, wherein the mandrel includes a plurality of said cantilever idler rollers arranged and spaced apart in a closed loop.
5 A mandrel assembly according to claim 4, wherein the closed loop includes the spaced idler rollers and the drive roller.
6 A mandrel assembly according to claim 4 or 5, wherein the or each idler roller passes through a respective bearing in said first plate and is fitted to a second plate displaced behind the first plate.
7 A mandrel assembly according to claim 6, wherein the or each bearing is a self-aligning bearing.
8 A mandrel assembly according to claim 6 or 7, wherein the first plate is rotatably fixed to a spacer separating it from the second plate, and is able to rotate in a vertical plane relative to the second plate.
9 A mandrel assembly according to any one of the preceding claims, wherein the drive roller includes an extended portion for engagement by a connecting sleeve.
A mandrel assembly according to claim 9, wherein the connecting sleeve is attached to the rotating means so that the drive roller may be driven.
11 A mandrel assembly according to any one of the preceding claims, whether the driver roller includes a surface treatment to assist in driving engagement with and subsequent advancement of said strip.
12 A mandrel assembly according to any one of the preceding claims, wherein the drive roller is positioned so that it to extends substantially perpendicular to the incoming strip forming the tubular product.
13 A mandrel assembly according to any one of the preceding claims, wherein the mandrel assembly is mounted for rotation about an axis generally parallel to the plane of said first plate, whereby to offset the alignment of said idler rollers to an angle to correlate with the travel of the material forming said tubular product doing so with a helix of predetermined dimension.
14 A mandrel assembly according to claim 13, wherein the angle is 1° to 4°.
15. A mandrel assembly according to claim 13 or 14 wherein, while said idler rollers are offset at said angle, said drive roller is positioned so that it extends substantially perpendicular to the incoming substrate forming the tube.
16. A mandrel assembly according to claim 15, wherein said perpendicularly extending disposition of the drive roller arises from relative rotation of said first and second plates about an axis normal to their planes to compensate for said rotation of the mandrel assembly.
17 A winding station for manufacturing a tubular product, the winding station including:

a first plate;

a drive roller extending form the first plate;

at least one idler roller extending from the first plate; and means to rotate the drive roller;

wherein the drive roller and the at least one idler roller are arranged for the drive roller to engage and advance a strip to the at least one idler roller to wind the strip about the rollers to form a tubular product.
18 A winding station according to claim 17, wherein the drive roller is located at the top dead centre of the mandrel.
19 A winding station according to claims 18 or 19, wherein the mandrel includes a plurality of said cantilever idler rollers arranged and spaced apart in a closed loop.
20 A winding station according to claim 19, wherein the closed loop includes the spaced idler rollers and the drive roller.
21 A winding station according to claim 19 or 20, wherein the or each idler roller passes through a respective bearing in said first plate and is fitted to a second plate displaced behind the first plate.
22 A winding station according to claim 21, wherein the or each bearing is a self-aligning bearing.
23 A winding station according to claim 21 or 22, wherein the first plate is rotatably fixed to a spacer separating it from the second plate, and is able to rotate in a vertical plane relative to the second plate.
24 A winding station according to any one of claims 17 to 23, wherein the drive roller includes an extended portion for engagement by a connecting sleeve.
25 A winding station according to claim 24, wherein the connecting sleeve is attached to the rotating means so that the drive roller may be driven.
26 A winding station according to any one of claims 17 to 25, whether the driver roller includes a surface treatment to assist in driving engagement with and subsequent advancement of said strip.
27 A winding station according to any one of claims 17 to 26, wherein the drive roller is positioned so that it to extends substantially perpendicular to the incoming strip forming the tubular product.
28 A winding station according to any one of claims 17 to 27, wherein the mandrel assembly is mounted for rotation about an axis generally parallel to the plane of said first plate, whereby to offset the alignment of said idler rollers to an angle to correlate with the travel of the material forming said tubular product doing so with a helix of predetermined dimension.
29 A winding station according to claim 28, wherein the angle is 1° to 4°.
30 A winding station according to claim 28 or 29 wherein, while said idler rollers are offset at said angle, said drive roller is positioned so that it extends substantially perpendicular to the incoming substrate forming the tube.
31 A winding station according to claim 30, wherein said perpendicularly extending disposition of the drive roller arises from relative rotation of said first and second plates about an axis normal to their planes to compensate for said rotation of the mandrel assembly.
