    • A device is described for aligning coiled sheet material in the die of a power press during stamping operations. It includes a coiled sheet material feeder having a pair of powered gripping rollers for gripping and advancing the sheet material, these rollers being mounted on a head portion which is supported on a base with the feeder head being arranged to pivot on the base about a vertical axis and to move on the base laterally to the direction of travel of the sheet material while being fixed against movement parallel to the direction of travel of the sheet material. Hydraulic cylinders are provided for separately laterally moving forward and rearward portions of the feeder head and these are operatively connected to detector means, such as feeler actuated solenoid valves positioned along one side of the travel path of the sheet material between the feeder head and power press. These detector means sense the edge of the sheet material passing through the power press and cause the feeder head to laterally adjust and/or pivot to maintain the sheet material in proper alignment within the press.

    • 1517743 Guiding webs UNIROYAL Inc 14 July 1975 [1 Aug 1974] 29408/75 Heading B8R A web, e.g. of tyre building fabric, is guided transversely by rollers mounted on carriages which are urged towards each other simultaneously so that the rollers are urged into contact with opposite side edges of the web. In a first embodiment, the web is guided in a vertical plane between pairs of freely rotatable rollers lla, 11b, 25c, 25d, &c., Fig. 1, whilst rollers 37c, 37d, 39c, 39d &e., on carriages 17, 19 guide the web transversely. The carriages, slidably mounted on shafts 13, 15, are interconnected by linkage 45, 47, 49, 51 and are urged towards each other by a counterweight 61. In a second embodiment, Fig. 4, the web 203 is guided horizontally on roller balls 111 and the roller carriages 121, 123 are biased together via springs, e.g. 161. Additional overhead rollers, e,g, 184 prevent the web from riding up and a magnetic web brake associated with a transverse cutting device, is provided.
