Abstract
Abstract A guiding system for a strip of material, such as cardboard or plastic, passing through a machine which processes the strip and having at least one work station, for example a cutting station, fitted with a lower bed and an upper platen carrying tool holder plates between which the strip is processed, employes at least two laterally adjustable guides arranged between the tool holders and extending substantially the length of the platen in the direction of strip movement. At least one of the guides is resiliently mounted for momentary lateral movement, both of the guides being mounted for independent lateral positioning and coupled together for mutual lateral positioning.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
242 words
A guiding system for a strip of flexible material passing through a machine which processes the strip and which includes a work station having a lower bed and an upper platen which carry tool holder plates between which the strip is processed and between which the strip may arch vertically, said guiding system comprising: a first laterally adjustable guide between the tool holders; a second laterally adjustable guide between the tool holders, spaced from and parallel to said first laterally adjustable guide, said first and second guides receiving the strip therebetween and extending substantially the length of the platen in the direction of strip movement; first support means mounting said first laterally adjustable guide in the space between the upper platen and the lower bed; second support means mounting said second laterally adjustable guide in the space between the upper plate and the lower bed; resilient means connected between one of said laterally adjustable guides and its respective support means to permit momentary lateral movement of that guide in response to width variations of the flexible strip; a transverse guide at the input end of and spaced above the lower tool holder plate; a second transverse guide at the output end of and spaced above the lower tool holder plate; each of said transverse guides comprising a metal band secured at its ends under tension; and said transverse guides limiting vertical distortion of the strip as it moves between the tool holders.
