Abstract
Abstract There is disclosed a textile package which offers the advantages of strength, ease of assembly, and low cost. A plastic hub is passed through a hole in each end panel. The hub consists of a flat section for bearing against the outer face of an end panel, a large central sleeve which passes through the hole in the end panel and is inserted into one end of a central connecting tube, and several peripheral lugs which pass through smaller holes in the end panel which surround the central hole. The hub is secured to the end panel by nuts on the inner face of the end panel placed over the lugs, and the central sleeve is secured to the connecting tube by circumferential sharp-edged ridges. Looking at the package from outside an end panel, the central sleeve is hollow as are one or more of the lugs. This permits each end panel to be fixed to a mandrel so that the package can be turned as fabric is wound around the connecting tube. After the winding operation, a cardboard wrapper is placed around and stapled to the edges of the end panels.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
251 words
A textile package comprising a pair of end panels having edges; each of said end panels having a central hole therein and at least one additional hole positioned between said central hole and an edge thereof; a pair of connector elements each including a flat flange, a central sleeve projecting from the inner face of said flange and at least one lug projecting from said inner face in the direction of said sleeve, each said sleeve being inserted in the central hole of an end panel with said at least one lug passing through said at least one additional hole in each end panel; at least one locking means on said at least one lug on each connector element securing the connector element to each end panel; a hollow connecting tube positioned between said connector elements with the sleeves being received in the hollow ends thereof; the sleeve on each connector element being tapered with the diameter of its end furthest away from the flange being smaller than the inner diameter of said tube and having a plurality of sharp-cornered circumferential ridges, the outer diameter of at least one circumferential ridge near the flange being larger than the inner diameter of said tube so that a force-fit is achieved by said at least one circumferential ridge deforming the tube slightly and opposing the withdrawal of the sleeve from the tube; and a wrapper extending from one end panel to the other and being secured to the edges of both end panels.
Claim 2
Dependent Claim
251 words
A textile package comprising a pair of end panels having edges; each of said end panels having a central hole therein and at least one additional hole positioned between said central hole and an edge thereof; a pair of connector elements each including a flat flange, a central sleeve projecting from the inner face of said flange and at least one lug projecting from said inner face in the direction of said sleeve, each said sleeve being inserted in the central hole of an end panel with said at least one lug passing through said at least one additional hole in each end panel; at least one locking means on said at least one lug on each connector element securing the connector element to each end panel; a hollow connecting tube positioned between said connector elements with the sleeves being received in the hollow ends thereof; the sleeve on each connector element being tapered with the diameter of its end furthest away from the flange being smaller than the inner diameter of said tube and having a plurality of sharp-cornered circumferential ridges, the outer diameter of at least one circumferential ridge near the flange being larger than the inner diameter of said tube so that a force-fit is achieved by said at least one circumferential ridge deforming the tube slightly and opposing the withdrawal of the sleeve from the tube; and a wrapper extending from one end panel to the other and being secured to the edges of both end panels.
Claim 3
Dependent Claim
75 words
A textile package in accordance with claim 1 wherein the sleeve and said at least one lug on each connector element is hollow in a direction looking at an end of the package whereby a mandrel having a conforming shape including both a central sleeve and at least one lug can be placed up against the connector element at each end of the package to control turning of the package during a fabric winding operation.
Claim 4
Dependent Claim
38 words
A textile package in accordance with claim 2 wherein the inner end of each of said sleeves has a hole therein for permitting a bar to be inserted all the way through said tube and said connector elements.
Claim 5
Dependent Claim
38 words
A textile package in accordance with claim 1 wherein the inner end of each of said sleeves has a hole therein for permitting a bar to be inserted all the way through said tube and said connector elements.
