Abstract: A system for recovering hot-melt materials for reuse in a glue gun includes a flexible mold form mounted in a carrier and having an internal cavity that approximates the dimensions of the preformed hot-melt sticks. In order to change from one type hot-melt material to another, the sticks of the desired material are loaded into the gun while the heated, hot-melt material in the gun is discharged into the mold form. The hot-melt material flows into the mold form and assumes the shape of a conventional preformed stick. After cooling and solidification of the material, the mold form is removed from its carrier and the cooled, cast stick is removed from the mold form for reuse. The mold form is fabricated from a flexible, heat-resistant material, such as a silicone rubber, and includes an elongated tubular portion having a tapered exterior to facilitate removal from its carrier and an internal bore dimensioned to produce a cast stick having the dimensions of the preformed stick.

Abstract: A concrete column form structured to receive concrete therein for hardening into a building column having a curvilinear exterior surface. The form includes at least two form portions having a flat, thin generally rectangular sheet of resilient material and an elongated, rigid, straight edge bar connected along opposing side margins of each sheet. Each sheet is flexible by manipulation into a curvilinear configuration along its length by opposing rotation and inward movement of each of its connected edge bars. Connected together in side-by-side fashion along adjacent edge bars, the plurality of curvilinear-configured form portions complete the form itself. Both cylindrical and tapered building columns may be easily fabricated either in place or in a factory utilizing this invention.

Abstract: The present invention relates to a device for moulding cylindrical pieces, comprising, on the one hand, a tube made of a rigid, elastic material, split longitudinally and tending to expand transversely under the action of its inherent elasticity and, on the other hand, holding members capable, when they cooperate with said tube, of obliging the internal cavity thereof to take a reduced section corresponding to that of said pieces to be moulded and, when they do not cooperate with said tube, of allowing said internal cavity to take an expanded section. The invention is more particularly applicable to the moulding of tubular pieces, particularly from a laminate of supple fabric impregnated with polymerizable resin.

Second latch structures mounted on the lower ends the jackets are operable to hold the pallets in assembled relation with the jackets. Control linkage operably connected to both the first latch structures and second latch structures is operable to sequentially operate the first and second latch structures to open and close the jackets and release and hold the pallets.

Abstract: A tapered mould consisting essentially of a rigid outer frame formed of a set of radially arranged longitudinally extending guide members and a set of axially spaced encircling rings, and a gapped frustoconical tubular casing of resilient sheet material having a set of longitudinal stiffening members arranged thereon for sliding engagement with the respective guide members. The gap in the wall of the tubular casing, extending along a longitudinal line on the periphery of the casing, is opened and closed automatically as the tubular casing inserted in the outer frame is moved axially in opposite directions. Labor - consuming bolt - clamping and releasing operation is completely eliminated and the mould operation can be mechanized with ease, as desired. Packing means interposed between a pair of stiffening members arranged on the opposite sides of the gap further ensures leak - proof gap closing.
