Abstract: In apparatus for handling molded plastic articles, some of which are to be segregated, the improvement comprising a rotatable screw conveyor and adjacent, opposite support bar forming a path for the articles between them, such bar having a retractable portion to allow articles to either move out of or proceed along the path depending on the position of the retractable portion, and a reciprocable plunger operable with the retractable portion on receipt of a suitable control signal generated by a temperature sensing controller upstream of the retractable portion.

Abstract: In trimming moils from plastic articles with a blade interposed in a path along which the articles are moving while engaged with fixed and moving guides, the improvement downstream of the blade is provided of a rotatably driven moil discharge wheel and an opposite cooperating anvil forming a moil discharge path between them. The process improvements involve engaging the moil after cutting by the blade with the surfaces of the wheel and anvil and conveying the engaged moil along a path away from that taken during cutting by means of the revolving wheel.

Abstract: In trimming moils from plastic articles with a blade interposed in a path along which the articles are moving while engaged with fixed and moving guides, the improvement is provided of a retractable blade assembly movable between operative and inoperative positions by fluid motor power to permit passing articles through the path either while being trimmed or not, depending on up or downstream conditions. Means may also be included for shifting one of the guides, preferably the stationary one, into and retracted from its operative position on one side of such path.
