Abstract: A thermal translator device providing improved performance and faster expansion response, is described. Also described is an extrusion apparatus including a plurality of thermal translator devices operatively arranged for thermally actuated, localized action upon the lip. The thermal translator device includes a thermal energy source disposed within a structural member. The thermal energy source and the structural member are an integral unit. Also described is an extrusion apparatus including tie rods for a support assembly otherwise without support.

Abstract: An improved extrusion apparatus having an internal deckle, includes a toothed rack and a rotatable gear for positioning the deckle. The apparatus may include an independently adjustable, upstream deckle. A brake mechanism that assists the control of deckle movement, is also provided. A tongue and groove, sliding fit of the deckles may be used.

Abstract: The present invention provides an extrusion apparatus having an improved mechanism for thermally-controlled, lip gap adjustment. The apparatus includes a flow path for a gaseous cooling medium, in which flow path a plurality of temperature-responsive, lip gap adjustment members are disposed. In contact with each such adjustment member is a heating element.

Abstract: The present invention provides an extrusion apparatus having an improved mechanism for thermally-controlled, lip gap adjustment.

Structurally associated with each such adjustment member is a heating wire.

Abstract: An arrangement for actuating welding guns to weld weldment components in a predetermined welding pattern wherein the weldment components are movable relative to the welding guns. Movable means are movable in synchronism at a predetermined reduced speed in relation to the speed of the movable weldment components with means on the movable means corresponding with the desired welding pattern to be formed on the weldment components. Scanner means are electrically connected to the welding guns and are responsive to the indicating means to sequentially activate and deactivate the welding guns to weld the weldment components and form the predetermined welding patterns thereon. Limit switch means are electrically connected to the welding guns and means are provided on the movable means to actuate the limit switch means when the weldment components have completed their movement relative to welding guns to deactivate the welding guns.

Abstract: Support means have connected therewith a plurality of spaced members which guide and maintain reinforcing members in position as they are welded to a weldment component. Means are associated with the support means for simultaneously moving the spaced members longitudinally of the support means and additional means are provided with each of the spaced members for independently and selectively moving them longitudinally of the support means.

Abstract: A support arrangement for feeding a continuous strand of welding rod includes shaft means with laterally extending means mounted in spaced relation to one end thereof with spindle means being mounted on the laterally extending means. The other end of the shaft means is received in a tubular housing which includes a lateral extension thereon with spindle means extending in opposed relation to the spindle means on the lateral extending means for receiving and supporting a spool thereon. Bearing means support the tubular housing and the shaft means to accommodate rotation of the shaft means and the spool supported thereon and cooperating friction brake means are mounted adjacent one end of the shaft means for restraining rotation of the shaft means in a desired manner.
