An improved textile spool having a removable plug element inserted at the one or both ends of the hollow tube of the spool, the plug element having a tongue element therein extending axially and inwardly when the plug is engaged within the end of the spool, the tongue element having a raised projection on its outward external surface, and the hollow tube having a circular passageway therein, whereby, in the assembled condition, the projection fits in an interlocking relationship within the passageway, and whereby the plug element may be easily removed by an axial outward force when the tongue element is moved out of an interlocking relationship.

The inventive reel has two parts preferably made of plastic. One reel part comprises a first central hub section having a reel flange floatingly supported thereon, to move over the length of the first hub section between limits fixed by stops formed on opposite ends of the hub section. A parallel wire spring extends from the top of the first hub section to apply balanced forces against the floating flange, for biasing it to move toward the opposite reel flange. The second reel part comprises an integral flange and a second hub section upstanding thereon. A socket in the top of the second hub section seatingly receives the bottom of the first hub section. The reel is primarily designed for use with a tape or film strip which has a stiff leader which is slightly wider than the film itself. When the leader is placed between the two flanges, the floating flange must move against the urging of the wire spring to a spacing which securely captures the leader and loosely receives the tape or film between the flanges. The first reel, which has the floating flange, is removable from the assembly leaving the second reel which may be utilized in the threading of film which does not include a stiff leader required for automatic threading.

A method and apparatus for controlling stock tension as it is withdrawn from a coil in which a coil support is mounted for rotation about an axis transverse to the direction of withdrawal of stock from the coil and also for limited shifting movement along a path lengthwise of the direction of stock withdrawal. Shifting movement of the coil support in the direction of stock withdrawal is yieldably opposed with a generally uniform biasing force and the rotation of the coil about its axis is variably braked in response to shifting of the coil along said path to maintain the exiting tension on the stock substantially equal to the biasing force.

Dye tube for yarn in which flexible uprights spaced circumferentially around the axis of the tube and unsupported except at each end accommodate yarn shrinkage forces by bowing and recover their original diameter upon removal of the yarn, thereby allowing reuse, and uprights and top and bottom base portions of the tube define dye openings for high dye saturation.
摘要:
A knockdown reel comprising a tubular hub and having a pair of similar end flanges disconnectably attached to opposite ends of the hub by latching means capable of being released in order to separate the end flanges from the hub and thereby minimize the space consumed by said components in packaging, shipping and storing reels of this type. Actuation of the latching means is possible either manually or by relatively simple tools. The hub also may be made of a plurality of separable parts to further facilitate compactly arranging the components for the purposes described.

An improved collapsible yarn dye tube assembly is disclosed comprising two tubular members, one of which telescopes an initial limited distance into the other. Both tubular members have an outer end and an inner end with the telescoping arrangement taking place at the inner ends thereof. A plurality of openings or perforations around the tubular members and extending at least a major portion of the length thereof permit dye liquor to pass therethrough when yarn is wound around the dye tube and the package is placed in a dye kettle. The outer ends of the tubular members possess thickened wall portions so as to permit an abutting relationship between adjacent dye tubes whereby a solid relationship is established and whereby pressure transmitted from one dye tube to the next for collapsing thereof is evenly transmitted along the tube. Dye spindle alignment means are also provided on the inner periphery of the members to center the yarn package around the dye spindle. Alignment means may also be provided at the inner ends of the tubular members to prevent blockage of the perforations upon collapse of the dye tube. Further, the dimensions of the assembled dye tube establish driving contact between the tube and a winder drum at least at both outer ends and the middle of the assembly to improve winding the package produced.

A spool for wire and like products, comprising a generally cylindrical body portion so arranged that the spool separates into two substantially identical halves along a transverse plane which is perpendicular to the spool axis and is located preferably substantially intermediate the ends of the body portion. The joining or engaging parts of the body portion are keyed to each other against turning and are prevented from separation by novel means arranged so that the securement or clamping action thereof is enhanced by the force exerted by the wire or similar material which is wound on the spool. In the main embodiment of the invention the body halves have quarter-segment splined portions and quarter-segment keyways receiving the spline portions, all said spline portions having circumferential clamping grooves which become aligned to constitute a single annular groove which is completely filled by the beginning turns of the wire which is wound on the body portion. The beginning turns thus lock the body portions to each other.

A collapsible metal reel having a cylindrical barrel with a plurality of peripherally spaced tabs extending from each of its ends and having heads on each end of said barrel. Each head has an annular wall member with radially extending ribs attached to its outer face with arcuate brace members secured at their opposite ends to said radially extending ribs. The arcuate brace members have a surface parallel to the tabs of said cylindrical barrel. Slot means are formed radially outwardly from the arcuate brace members into which the tabs of the barrel are matingly engaged. Resilient fastening means are inserted in radially aligned apertures in said arcuate brace members and the tabs on the ends of said barrel to detachably secure said head to the barrel to provide a quickly assembled and disassembled reel structure.
