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.
Claims20
A method of wrapping fabric around a truss for a bedding foundation, the method comprising:
- providing a roll of fabric supported by a fabric support;
- providing a wrapping apparatus comprising two sides and braces extending between the sides, a truss holder movable between raised and lowered positions by pneumatically controlled cylinders secured to a front brace, a first vise mechanism secured to one side of the apparatus, a second vise mechanism secured to another side of the apparatus and a rotatable tension roller surrounding a shaft, the shaft extending between bearing assemblies attached to the sides of the apparatus;
- passing fabric from the roll of fabric through the wrapping apparatus;
- activating one of the vise mechanisms to move the vise mechanism in a linear direction towards the other vise mechanism to pinch the truss between the vise mechanisms;
- stapling the fabric to an upper surface of the truss to create an initially stapled truss;
- moving the truss holder to its lowered position;
- rotating the initially stapled truss with the vise mechanisms to create a wrapped truss;
- moving a carriage in a first direction over the wrapped truss with a linear actuator, a stapler secured to the carriage further stapling the fabric to the wrapped truss;
- and
- moving the carriage in a second direction opposite the first direction over the wrapped truss to cut the fabric to create a finished truss.
