Abstract
An apparatus for upholstering a truss allows an operator to staple a fabric web to the truss, rotate the truss, further staple the semi-finished truss and cut the fabric web. The truss is fully upholstered after the end surfaces of the truss are wrapped up in fabric and the fabric stapled in place. The apparatus may accommodate different size trusses. A web of fabric is pulled around at least one roller in the apparatus by rotation of two vise mechanisms on opposite sides of the truss.
Claims7
A method of upholstering a truss for a bedding foundation, the method comprising:
- providing an apparatus comprising a base, two sides secured to the base, a truss table movable between raised and lowered positions;
- inserting a truss onto the truss table between clamps;
- moving a first vise mechanism towards a second vise mechanism to pinch the truss between jaws of the first and second vise mechanisms;
- at least one of the first and second vise mechanisms being movable to pinch the truss between the vise mechanisms so the vise mechanisms rotate the truss with the truss fixture table in a lowered position;
- stapling a fabric web to the truss;
- lowering the truss table so the truss is supported by only the vise mechanisms, creating a suspended truss;
- rotating the suspended truss by rotating the vise mechanisms to wrap the suspended truss in fabric;
- cutting the fabric web;
- further stapling the fabric web to the suspended truss to create a semi-covered truss;
- and
- separating the vise mechanisms to allow the semi-covered truss to be separated from the apparatus.
