A method of guiding a strip (S) of material, e.g. steel, comprises feeding the strip between a pair of spaced guide members (15), through pinch rolls (13) and optionally on to a winder (12) to be coiled. When the strip passes the upstream end of the guide members (15), in a first stage of the method, the members are moved inwardly to narrow the gap between them to a predetermined size greater than the width of the strip. When the leading end of the strip enters the pinch rolls (13), in a second stage of the method, the members move together to further narrow the gap between them. The second stage may, be governed in response to the output from sensors (17, 18) which detect the width of the strip and the position of its centre. The positions of the guide members (15) may be continuously varied to accommodate the varying width of the strip. By varying the position of the centre line of the strip with respect to a mandrel around which the strip is wound, a coil may be produced having a uniformly wound portion affording a flat surface, which portion protrudes on one side of the coil.
A method of guiding a strip of material comprising feeding a leading end of the strip into a guide assembly which defines a gap between parallel guide members through which the strip may pass and narrowing the gap in two stages while maintaining the guide members parallel to each other, the first stage occurring on the introduction of the leading end of the strip into the upstream end of the guide assembly, the second stage occurring on or after engagement of the leading end of the strip with pinch rolls downstream of the guide assembly.
