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.
