Process and apparatus are herein described for shearing and alternatively directing a continuously produced strand into or away from a strand collection device, particularly a pot spinning device. The novel apparatus is located between a strand producing unit and a collection unit and includes an elongate upright funnel with a transverse slide at the lower outlet of the funnel. The slide carries a straight tubular section and an angular tubular section, with a cut-off blade between the sections. The slide is reciprocated to bring either of the two sections into register with the outlet of the funnel, with the blade serving to sever the strand as the slide is moved to either position. When the staight section is in register, the strand enters the collection unit. When the angular section is in register, the strand is diverted away from the collection unit. The device is particularly used when operation of the collection unit is interrupted while allowing strand production to continue.
Apparatus for alternatively feeding or diverting a continusouly produced strand to or from a location where the strand is to be collected said apparatus comprising the combination of a first conduit means for guiding the strand toward said location, said first conduit means having an outlet spaced from said location, second conduit means movable into registry between said outlet for guiding the strand from said first conduit means to said location, third conduit means movable into registry with said outlet for guiding said strand away from said location, means for alternatively moving either of said second or third conduit means into registry with said outlet, and means for severing said strand at said outlet upon movement of either of said second or third conduit means into registry with said outlet.
In combination with apparatus for continuously producing a strand from a production unit and collecting the strand in a collection unit below the production unit, an apparatus for shearing and deflecting said strand toward and away from said collection unit, said apparatus comprising an upright funnel receiving the strand from the production unit, an outlet at the lower end of said funnel spaced from the collection unit, and a slide mechanism between said outlet and said collection unit, said slide mechanism comprising a slide movable transversely to the axis of the funnel, said slide being movable between a collection unit feeding position and a diverting position, a pair of spaced pipes depending from said slide, the inlets of respective pipes being alternatively in registry with the outlet of said funnel with said slide in its respective positions, one of said pipe sections being straight and communicating with said collection unit with said slide in feeding position, the other of said pipes having a bend therein leading away from said collection unit with said slide in said diverting position, and means associated with said slide for severing said strand upon movement of said slide from one position to another.
