ABSTRACT:
The present invention is an apparatus to attach a continuous sheet of flexible material, such as fabric, to pairs of elongated rigid members such as wooden slats. The flexible member is attached on each side to one of the pairs of rigid members. A table supports the apparatus and has recessed guides longitudinally located on each side of the table. A magazine holder overlays each of the guides and each magazine holds a plurality of elongated rigid members in an aligned, vertically stacked, relationship. A pair of slides advances a pair of the rigid members, one along each guide to a first drive mechanism. The first drive mechanism advances each of the pair of elongated rigid members at a constant linear speed into an attachment zone. Flexible material is also guided into the attachment zone to lay atop each of the elongated rigid members. A pair of staplers, one overlaying each guide drives staples through the flexible material into the rigid members to attach the flexible material to each of the elongated rigid members. Subsequent elongated rigid members are automatically advanced into the attachment zone for continuous assembly.
