Abstract
A first member supported at one of its ends for rotation and against axial displacement is formed with a uniform outer surface along one of its longitudinal sides and a tapered surface opposite thereto. A second member, formed with a tapered surface on one of its sides and a uniform surface opposite thereto, is disposed with its tapered surface cooperating with the first member''s tapered surface. A rod secured to the second member extends through an orifice in the fist member to facilitate longitudinal displacement of the second member on the first and a corresponding change in the size of the mandrel diameter. A resilient shroud encompasses the length of the mandrel.

BACKGROUND OF THE INVENTION Field of Application This invention relates to winding mandrels.
SUMMARY OF THE INVENTION It is an object of this invention to provide an improved winding mandrel or spindle.
Yet another object of the invention provides improved spindle means for winding a web and which permits an easy removal of a completed web roll therefrom.
These objects, and such other objects as will hereinafter appear, will become apparent from the following description of preferred embodiments of the present invention as shown in the accompanying drawings, in which:
BRIEF DESCRIPTION OF THE DRAWINGS FIG. l is a detail view of a novel spindle or mandrel for winding a web;
FIG. 2 taken as a whole comprises a detailed perspective of the spindle shown in FIG. 1; and
FIG. 3 is a right end view ofthe said spindle.
DESCRIPTION OF THE PREFERRED EMBODIMENT With reference to FIGS. 1 and 2 there is generally shown at 24 a spindle or mandrel which includes two parts with flat matching tapered surfaces along their longitudinal lengths. The sides adjacent said tapered surfaces are each substantially flat surfaces, while the sides opposite the tapered surfaces are of convex configuration. When the two parts are placed in cooperating position relative to each other along the tapered surfaces said convex surfaces form the spindle as circular in shape and of a given normal diameter, which in the instant case is approximately l inch. One said tapered part forms the main or body section of the spindle which is supported by ball bearing means 230 mounted within the forward and rearward plates 22, 22' comprising a turret. Said body section has fast to one end thereof a gear 133 suitably driven. The second tapered section of the spindle is slidable longitudinally along the tapered surface of the body section. Both said sections are rotated as a unit by means of the projections 231 thereon engaging corresponding slots 232 of the respective sections. Suitable set pins when inserted in holes 233 to extend through related slots 234 in projections 231 will serve to lock the two halves of the spindle together.
Extending within the drilled shank portion 229 of the body section is a plunger 1134 provided with a slotted end 235 for receiving a projection 236 of the slidable section of the spindle. Said plunger having suitable pin and open end slot engagement at 237 with projection 236. Nested within shank end 229 is a compression spring 239 which biases plunger 134 and thereby the slidable section of the spindle inwardly, or toward the left as viewed in FIG. ll. Thus, in normal winding condition the left end of the slidable section will be held against a shoulder 240 ofthe body section.
Encompassing the spindle or mandrel 24' is a metal shroud 241 made of spring-tempered material, such as beryllium copper, and which is biased to conform with the circular configuration of the spindle 24'. To assure rotation with the spindle, shroud 241 includes a split seam along the full length thereof and one edge of the seam is bent inwardly to form a tongue 242 engaging a cooperating longitudinal groove 243 cut along the length of the body section ofthe spindle.
Pivotally mounted upon a stud 244, (FIG. l) secured through suitable means (not shown) to turret plate 22', is a bellcrank lever 245, one end of which engages the end face of plunger 134. On the other end of bellcrank 245 is mounted a roller 246 adapted in the indexing rotation of the turret to impart a clockwise movement, as viewed in FIG. ll, to said bellcrank. Upon clockwise movement of bellcrank 24S, plunger 134 is displaced rightwardly, forcing `the slidable section of the spindle to move rightwardly therewith and along the tapered surface indicated by the line 249. During said movement, the fully webbed spindle 24' is caused thereby to :collapse to a reduced diameter and shroud 241 also collapsing therewith releases its frictional hold of the coiled web, so that the web may now be easily removed by the operator.
Following removal of the web coil, roller 246 is freed, bellcrank 245 is returned, and compression spring 239 -will restore the spindle 24' and associated parts to their leftward normal condition. A suitable setscrew 238 in the outer end ofthe spindle serves by engaging tongue 242 to prevent a displacement of shroud 241 during said removing of a web coil from the spindle. For better friction with the web, shroud 241 is covered with a synthetic rubber material, such as the synthetic well known to the art as Viton Also, to increase the gripping properties thereof in the circumferential direction while at the same time decreasing such property in the axial direction, said covering herein is scored along the surface thereof with close circumferential grooves.
While there has been shown and pointed out the fundamental novel features of the invention as applied to a preferred embodiment thereof, it will be understood that various omissions, substitutions, and changes in the form and details of the devices illustrated in their operations may be made by those skilled in the art, without departing from the spirit of the invention. It is therefore to be limited only as indicated by the scope of the following claims:
What is claimed is as follows:
ll. A winding mandrel for a coiling machine, said mandrel comprising a member supported at one end for rotation and against axial displacement, having a uniform outer surface along a longitudinal side perpendicular to the axis of rotation and a surface opposite thereto tapered toward the distal end for substantially the length thereof;
a member having an outer surface corresponding to the first said outer surface and a tapered surface cooperable with the first said tapered surface; the second said member slidably mounted upon the first said member along said tapered surfaces; whereby a relevant longitudinal displacement between said members reduces the mandrel in its diameter between said outer surfaces;
said first-named member having a longitudinal orifice therein at the support end; and
a connecting rod supported therein secured to the secondnamed member and having its opposite end extending beyond said orifice for operation thereby to effect longitudinal displacement of said second-named member.
2. The invention according to claim ll and said orifice terminating as an enlarged diameter recess in said first-named member; and
a compression spring mounted within said recess, adapted for restoring and maintaining said connecting rod and thereby said second named member at a normal position providing a given diameter for said mandrel.
3. The invention according to claim 2 including a substantially circular resilient shroud encompassing substantially the length of said members comprising said mandrel;
said shroud being split along the entire length thereof;
a recess slot extending longitudinally along the length of the mandrel;
a tab formed along an edge of said shroud produced by said split therein and engageable with said recess slot for maintaining said edge against rotation on said mandrel; and
wherein said shroud expands and contracts in accordance with any change in the diameter of said mandrel.
4. The invention according to claim 3 and said shroud along the length thereof provided with closely adjacent concentric scores.
