Abstract:
1. An apparatus for tucking and securing a corner flap of a flexible cover sheet which extends across a front face of a workpiece and has edge flaps which wrap around edges of the workpiece and are adhesively secured to a back side thereof while creating corner flaps of the cover sheet which extend along and project rearwardly at corners of the workpiece, comprising: a support arrangement for stationarily holding a workpiece having a flexible cover sheet attached thereto and extending across a front face of the workpiece and corner flaps projecting rearwardly at corners of the workpiece; said support arrangement including a corner positioning structure defining a recess for accommodating a corner of the workpiece to permit stationary positioning thereof; said support arrangement also including a support surface for supportive engagement with an opposite-facing surface of said workpiece to transversely position said workpiece relative to said corner positioning structure; a corner flap tucking apparatus positioned adjacent said corner positioning structure at a location adjacent but outwardly of said recess; said corner flap tucking apparatus including a gathering plow movably supported adjacent said corner positioning structure and coupled to a first drive device which moves said plow forwardly from a retracted position wherein the plow is spaced outwardly from the workpiece into an advanced position wherein the plow is positioned over the corner of the workpiece, a forward end of said plow having a gathering notch for sidewardly gathering the corner flap into a more compact bundle as the plow moves forwardly over the workpiece; a contact member mounted on said plow for contacting the bundle as the plow moves forwardly and for causing the bundle to be folded over into contact with a back side of the workpiece; an activatable securing device for attaching the folded bundle to the workpiece when the plow is in said advanced position; and said plow being returned to said retracted position after said folded bundle is secured to said workpiece by said securing device.
