Abstract
A roll former comprises a bed and at least one roll forming member mounted on the bed, each roll forming member comprising a stand, a support member pivotally mounted on the stand for rotation relative to the stand about a selected axis, a pair of shaping elements mounted on the support member shaped to modify the shape of a member such as a purlin passed in use therebetween, and locating means to locate the support member in a selected one of a plurality of available positions relative to the stand.
Claims15
A roll forming member for shaping thin sheet material fed in a feeding direction relative to the roll forming member comprising:
- a stand;
- a support member;
- pivot means for mounting said support member on said stand so that said support member is rotatable relative to said stand about a selected axis extending at substantially right angles to the feeding direction;
- a pair of shaping elements mounted on substantially parallel axes on said support member and positioned with respect to each other so that in use each shaping element bears on one of the opposite surfaces of the sheet material, said shaping elements being shaped to modify the shape of the sheet material when passed therebetween said parallel axes of said shaping elements being parallel to said selected axis;
- and locating means for retaining said support member in a selected one of a plurality of positions relative to said stand and said selected axis so that the support member can be pivoted to permit each shaping element to bear against either side of the sheet material.
A roll former through which thin sheet material passes in a first direction comprising:
- a bed;
- and at least one roll forming member mounted on said bed comprising:
- a stand,
- a support member,
- pivot means for mounting said support member on said stand so that said support member is rotatable relative to said stand about a selected axis extending in a second direction substantially at right angles to said first direction,
- a pair of shaping elements mounted on substantially parallel axes on said support member and positioned with respect to each other so that in use each shaping element bears on one of the surfaces of the sheet material, said shaping elements being shaped to modify the shape of the sheet material when passed therebetween, said parallel axes of said shaping elements being parallel to said selected axis and
- locating means for retaining said support member in a selected one of a plurality of positions relative to said stand and said selected axis so that the support member can be pivoted to permit each shaping element to bear against either side of the sheet material.
