Abstract: Feeding apparatus for repetitively advancing an elongate workpiece to a saw cyclically operable to cut parts of uniform length from the workpiece includes a power-driven feed wheel frictionally engageable with the workpiece. The feed wheel is movable into and out of engagement with the workpiece so that the workpiece may be clamped in a stationary position while being cut. The feeding apparatus is provided with a manually controlled adjustment which enables the operator to adjust the feeding apparatus to compensate for wear of the feed wheel with little or no interruption of the production cycle.

Abstract: A filler carrier of the type adapted to move metal extrusions in a generally horizontal plane beneath the dispensing nozzle of a machine for dispensing uncured liquid plastic is disclosed. Uncured liquid plastic is dispensed into a channel of the extrusion which is subsequently cut so as to form a thermal barrier between the remaining sections of the extrusion which remain coupled by means of the cured plastic material. The filler carrier is provided with a mechanically driven conduit that is movable between a first lowered position that permits the passage thereover of the extrusion, to a second raised position wherein an upper opening of the movable conduit receives the nozzle of the dispensing machine so that uncured liquid plastic from the machine and any subsequent flushing solvent passing therethrough may be collected and transferred to an appropriate container in a clean and simple fashion.
