Abstract
A hemming tool is used to hem a roofing panel having a base portion, a pair of standing ribs extending in a longitudinal direction along opposing sides of the base portion, and a tongue section extending from the base portion beyond the standing ribs, for use in a standing seam roofing system. The hemming tool comprises a panel support supporting to roof panel thereon such that the tongue section extends outward beyond a free edge of the panel support. A die member having a working surface, for engaging the tongue section of the roofing panel, is supported by a die support linkage such that the working surface of the die member is arranged for rolling engagement with the tongue section of the roofing panel about the free edge of the panel support from an upper surface to a lower surface of the panel support.

A hemming tool for hemming a roofing panel having a base portion and a pair of standing ribs extending in a longitudinal direction along opposing sides of the base portion arranged for connection with ribs of adjacent roofing panels of similar configuration in which the base portion includes a tongue section extending in the longitudinal direction beyond the ends of the ribs, the device comprising:
- a main frame;
- a panel support mounted on the main frame and comprising an end portion having an upper surface and a lower surface joined to the upper surface along a free edge of the panel support, the end portion being arranged to support the base portion of the roofing panel thereon such that the tongue section projects beyond the free edge and is arranged to be hemmed about the free edge;
- a die member having a working surface arranged to engage the tongue section of the roofing panel supported on the panel support;
- and
- a die support linkage supporting the die member on the main frame such that the working surface of the die member is arranged for rolling engagement with the tongue section of the roofing panel about the free edge of the panel support from a starting position of the die member at the upper surface of the panel support to an ending position of the die member at the lower surface of the panel support.
A method of hemming a roofing panel having a base portion and a pair of standing ribs extending in a longitudinal direction along opposing sides of the base portion arranged for interlocking connection with ribs of adjacent roofing panels of similar configuration in which the base portion includes a tongue section extending in the longitudinal direction beyond the ends of the ribs, the method comprising:
- providing a hemming tool a panel support having an end portion with an upper surface and a lower surface joined to the upper surface along a free edge of the panel support and a die member having a working surface;
- supporting the base portion of the roofing panel on the end portion such that the tongue section of the roofing panel projects beyond the free edge of the panel support;
- engaging the tongue section of the roofing panel against the upper surface of the panel support with the working surface of the die member;
- rolling the working surface of the die member along the tongue section about the free edge of the panel support from a starting position at the upper surface of the panel support to an ending position at the lower surface of the panel support such that the tongue section is hemmed about the free edge of the panel support.
