Guide apparatus for the beading to connect the components of a cover for mattresses or the like

A guide apparatus for use with a beading machine to assemble beading connecting together a front component and a side strip of a mattress sheath supported by a rectangular mattress-shaped template comprising:

• a fixed base having a rectangular, perimetrically extending track;
• a beading machine mounted to move in one direction along the track during assembly of the beading;
• a rectangular frame for supporting the template;
• cooperating mounting means on the frame and base for mounting the frame on the base to extend in generally parallel relation thereto and with the sides of the frame diverging in the direction of movement of the beading machine at a small angle from the respective corresponding adjacent sides of the track thereby imparting a corresponding divergence to corresponding sides of a supported template, the respective sides of the frame and template being sequentially progressively urged towards the respective corresponding adjacent sides of the track by the beading machined during its passage of movement along the respective sides of the track;
• the mounting means including cooperating guide means on the frame and base, respectively, for limited guided movement of the frame on the base in orthogonal directions parallel to the sides of the track and in a plane parallel to the track;
• thrust means extending between the frame and the base operable resiliently to urge the frame in the orthogonal directions:
• means to operate the thrust means sequentially in synchronism with the position of the beading machine on the track thereby to activate the thrust means to urge the frame successively in respective orthogonal directions which are opposite to the respective directions of movement of the beading machine during its passage along the track thereby to bring the next adjacent corners of the frame, template and track successively into alignment in advance of the beading machine, the operating means being arranged to deactivate the thrust means during the passage of the beading machine through the corner to permit the frame to be freely moved on the guide means by the beading machine.
