The key is sized to fit into the keyway and has a projecting portion that projects outwardly from the shaft. The shaft has an axially extending shaft keyway. DISCLOSURE OF THE INVENTIONĪ forming roller adjustment system includes a shaft, a key, a roller and a ring. 5,787,748 to Knudson and Flood discloses variable panel forming apparatus with drive stations having upper and lower rollers each independently adjustable to accommodate different panel widths. 5,038,592 to Knudson discloses apparatus for making different residential and commercial building siding of different widths includes a series of roller stations with selective vertical roller positioning adjustments and selective axial lateral roller portion position adjustments. 4,899,566 to Knudson discloses a first group of stations that are adjustable to different width settings using the same rollers to form more than one width of ogee type gutter. 4,811,587 to Knudson discloses a laterally adjustable side carrier for making panels of different widths. ![]() ![]() Changing width with this system is also highly time consuming and demands extensive handling of either tools and/or parts. The precision fastener provides for both the torque and positioning functions. This type of system is complex and expensive.Ī third system includes a precision fastener threaded through a pre-drilled hole in the roller and into a specifically positioned hole in the shaft. In this case, the side structures which support and position the shafts are mechanically positioned or repositioned to form different profile widths. Changing width with this system is highly time consuming and demands extensive handling of either tools and/or parts.Īnother system uses keyways and keys for torque, and mechanical connection of the roller to a side support structure for positioning. In this case, repositioning of the rollers for different profiles requires the rearrangement of the spacers to achieve new positions along the shafts for the rollers. One such system involves using keyways and keys to transmit torque from the shaft to the roller, and sleeves or spacers of specific lengths mounted on the shafts for positioning. There are several prior known systems for lateral adjustment of rollers to accommodate forming different widths of products. Sheet metal roll forming machines that can produce more than one width of, for example, a metal building panel or rain gutter, are more versatile. Some prior known sheet metal roll forming machines were built to produce a single shape with a single width. ![]() The shafts of the rollers in the pair are driven in opposite directions to draw or feed the material through the machine. Each roller in a pair is mounted on a separate shaft and the sheet metal passes between the rollers in the pair. Each station includes a least one pair of forming rollers. Sheet metal roll forming machines generally have a number of longitudinally spaced forming stations that progressively bend a flat strip of sheet metal into the selected shape. The present invention relates to sheet metal roll forming machinery, and more particularly to a forming roller adjustment system.
