Abstract

A method and apparatus (10) for automatically installing in tandem pairs of protective covers to adjacent corners of a rectangular picture frame, to protect the corners during shipment, includes a pair of installation mechanisms (20) oriented at ninety degrees with respect to one another. When both adjacent corners of a frame have been fully inserted into and correctly oriented with respect to the installation mechanisms, sensors (160) within each mechanism produce a command signal which initiates simultaneous automatic operation of both installation mechanisms, each of which includes a feeder (60) that loads an individual pre-cut cardboard preform (40) into position in each mechanism. Each mechanism includes flap folder arms (121) which fit into worktable recesses (119), and which bend preform flaps (41) (42) (47) (50) and (51) to overlie adjacent members of a picture frame, and a pneumatic stapler gun (91) which inserts a staple downwardly through a right-triangular cover flap into a securement flap of the preform and a frame member, securing a separate folded corner protector over each frame corner.

Claims

AMENDED CLAIMS[received by the International Bureau on 31 May 2002 (31.05.02); original claim 1 amended; remaining claims unchanged (1 page)]
1. (Amended): A method for attaching in tandem protective covers to a plurality of corners of a frame, each of said corners being defined by the intersection at a dihedral angle of two adjacent elongated intersecting channel members comprising two adjacent
5 sides of said frame, said method comprising; a. placing said frame corners in a predetermined relationship to a plurality of spaced apart corner protector preforms, b. generating a sensing signal in response to each of said plurality of frame corners being simultaneously positioned in a predetermined alignment with said preforms,
L0 and c. automatically and simultaneously fastening each of said preforms to a separate corner of said frame in response to said sensing signal.
2. The method of Claim 1 wherein each of said corner protector preforms is further defined as comprising a thin sheet of flexible material, said sheet being foldable into a
L5 plurality of flaps.
3. The method of Claim 2 further including the step of folding each of said preforms over an adjacent corner of said frame in response to said sensing.
4. The method of Claim 1 wherein said plurality of corners of said frame is further defined as two.
20 5. The method of Claim 4 wherein each of said corner protector preforms is further defined as comprising a thin sheet of flexible material, said sheet being foldable into a plurality of flaps.
6. The method of Claim 5 further including the step of folding each of said preforms over an adjacent corner of said frame in response to said sensing. 25 7. The method of Claim 1 wherein each of said corner protector preforms is further defined as comprising a thin sheet of flexible material, said sheet being foldable into a plurality of flaps including:
(i) a vertically elongated rectangular spine flap having a width approximately equal to the thickness of said intersecting channel members, 30 (ii) a first generally right triangularly-shaped, lower cover flap having a vertical side coextensive with a first vertical longitudinal side edge wall of said spine flap, a base collinear and coextensive with the lower horizontal lateral base edge wall of said spine flap, and a hypotenuse which intersects the upper horizontal lateral edge wall of said spine flap, 35 (iii) a horizontally elongated, rectangularly-shaped side cover flap depending downwardly from said base of said first, lower cover flap, said side cover
