US 4,357,970 A · Tie ejecting apparatus in a bundling tie applying tool

Abstract

A tie scrap ejecting apparatus is provided in a bundling tie applying tool for positive controlled ejection of a portion of a bundling tie severed upon being suitably tensioned about a plurality of articles. The ejecting apparatus includes a plurality of tubes, interconnected for slidable, telescopic movement. The smallest of the tubes is coupled to a movable support that supports the tie severing means and is thereby movable therewith. The smallest tube has a passageway for close passage of a severed tie therethrough, the passageway communicating with the severing means. The largest tube is stationarily affixed to the housing, its opening communicating with a port of egress for discharging the severed tie portion. The other tubes are movable with respect to the largest tube, each of the movable tubes having an end surface that upon collapsing of the apparatus lies closely adjacent the port of egress for pushing a severed tie portion therethrough.

In a bundling tie applying tool for installing an elongate bundling tie about a plurality of articles to be bundled, said tool being of the type having a housing, means for severing a portion of said tie positioned about said articles and a port of egress on said housing for the discharge of said severed tie portion, tie ejecting apparatus comprising:

means within said housing defining an enclosed course extending from said severing means to said port of egress for receiving and containing therein a severed tie portion;
and
plunger means movable within said enclosed course to a position closely adjacent said port of egress for engaging and pushing therethrough a severed tie portion positioned in said enclosed course.

In a bundling tie applying tool for installing an elongate bundling tie about a plurality of articles to be bundled, said tool being of the type having a housing, means for severing a portion of said tie positioned about said articles, a movable support supporting said severing means and a port of egress on said housing for the discharge of said severed tie portion, tie ejecting apparatus comprising:

a plurality of telescopically slidable elongate hollow members defining a collapsible portion of an enclosed course extending from said severing means to said port of egress for receiving and containing therein a severed tie portion;
a first member of said plurality of members having an opening communicating with said port of egress and being stationarily affixed to said housing, the other members being slidably movable with respect thereto;
a second member of said plurality of members having a passageway extending longitudinally therethrough for close passage of a severed tie portion and being coupled to said movable support, said passageway being in communication with said severing means,
said telescopically sliding members, in response to the movement of said support, moving slidably from a first extended length to a second collapsed length,
each of said movable members having an end surface movable within said enclosed course, each end surface being positioned at said extended length to lie within said enclosed course longitudinally spaced from said port of egress and at said collapsed length to lie closely adjacent said port of egress.
