4 Claims. (01. 20659) This invention relates to end protectors for rolls of strip material, and more especially it relates to protectors for excluding moisture and water from the ends of rolls of material.
The invention is of especial utility for protecting rolls of tire-building fabric during shipment thereof under conditions Where moisture is present, such as in the holds of ships during transportation to overseas factories. Wetting of portions of the fabric results in localized shrinkage thereof, thereby resulting in non-uniformity of stretch characteristics and rendering the fabric unsuitable for its intended use. The fabric rolls consist of long lengths of the fabric wound or rolled upon rigid, cylindrical, axial spools or cores, usually composed of wood. Said cores are of greater length than the width of the fabric strips and project from opposite ends of the rolls. The extent to which the cores project may differ in different rolls, and also may differ at opposite ends of the same roll. The rolls are protected during shipmentby packaging them in waterproof paper. Enclosing the periphery of the rolled fabric is a relatively simple matter.
Due to the non-uniformity of the roll-ends as the result of the cores aforementioned, the enclosing of the roll-ends in a waterproof covering here tofore has been a difficult matter, and it is to the relief of this condition that this invention primarily is directed.
Accordingly, the chief objects of the invention are to provide an improved waterproof protector for the ends of rolled strip material; to provide a protector of the character mentioned that is easily and readily applied to a roll; and to provide a protector that is applicable to rolls of which the cores project different distancesfrom the ends thereof. Other objects will be manifest as the description proceeds.
Of the accompanying drawing:
Fig. 1 is a fragmentary perspective view of a roll of strip material for which the improved protector is provided;
Fig. 2 is a perspective view of the respective parts of one of the elements of the end protector, shown in separated relation;
Fig. 3 is a similar view of the respective parts of the other element of the end protector; and
Fig. 4 is a fragmentary side elevation of a roll of strip material, and the improved end protector in diametric section, operatively associated therewith:
Referring first to Fig, 1 of the drawing, there is shown a roll IU of strip material, such as fabric, that requires protection from moisture during shipment, and for which the improved roll-end protector is provided. The roll comprises an axial core H of wood or other suitable material, which core, as shown, projects from the end of the roll, it being understood that the core projects from the opposite end of the roll (not shown) in like manner, but usually to a slightly different extent.
When the roll ID is prepared for shipment, as shown in Fig, 4, it is enclosed in a package comprising a pair of roll-end protectors such as the protector A,- a pair of core-caps suchas the. corecap B, and a peripheral wrapper C, the said package components all composed of water-proof disc-like structure that abuts an end of the roll paper. Each package element-A is a composite, Ill with its perimeter flush or substantially flush with the periphery of the roll, and the wrapper C, which is somewhat wider than the length of the roll lil, has its marginal portions folded over onto the exposed face of the respective end protectors A, as shown at I 3, Fig. 4, and adhered thereto by waterproof glue or cement. Each end protector A is formed with an axial opening having a collar l6 circumscribing the same, the projecting end portions of the core II bein re ceived within said collars, The latter fitssnugly about the core II, and may extend to the ends of the core or slightly beyond, although the collar shown in Fig. 4 terminates somewhat short of the end of the core. Each core-cap B is a composite structure that fits over an end of the core I l and telescopes over the end portion of the collar l6 thereon, said cap being adhe'sively secured to said collar, in the region where cap and collar overlap, by waterproof glue or cement.
The constituent parts of the respective protector elements A are shown in Fig. 2; they consist of two identical axially apertured discs l5, a tubular collar l6, and an axially apertured disc I! of smaller outside diameter than the discs l5, all of which parts are composed of waterproof paper. The tubular collar I6 is longitudinally slit for about half its length at a plurality of points to provide a plurality of finger-like strips l8, l8, said strips being bent at right angles to the tubular wall of the collar so as to extend radially outwardly from one end thereof. The respective parts l5, l6 and I! are assembled in co-axial relation with the collar I5 extending through the axial aperture in one of the discs I5, the finger- .like strips l8 being fanned out between the discs l5, said parts being adhesively united with waterproof glue or cement. The disc I! is adhered to the exposed face of one of the discs I5 in circumscribing relation to the collar 15 that p j therethrough.
The constituent parts of the respective corecaps B are best shown in Fig. 3; they consist of an inner disc 20 of waterproof paper, a substantially similar outer disc 2! of the same material, and a sleeve-like annular member 22 that is of slightly larger diameter than collar It hereinbefore described; so as to be capable'of telescoping thereover, said member 22 also composed of waterproof paper. The member 22, like member l6 of element A, is longitudinally slit to provide a plurality of finger-like strips 2.3,, which strips are folded radially inwardly so as to be disposed in marginally overlapping relation. The parts 26, 2!, and 22 are assembled in co-axial relation with the disc 20 located within the member 22 and. the disc 2| located on the exterior thereof, the strips 23 of member 22 being confined between said discs. retained in assembled; relation by waterproof, glue or cement.
From the foregoing it will be apparent that the roll-end. protector: is of simple construction, is readily applied to a: roll of. material to be protected, can compensate for non-uniformity in the length of theprojecting: portions. of; the roll-core, and achieves the other advantageszsetout. in the foregoing statement. of objects.
It. will; be understood that the several elements of the tolls-package are not: drawn. to scale, but are shown of exaggerated thickness. for clarity oil illustration.
Modification. may be resorted to without departing from the spirit of; the invention, or the scope thereof as: defined by the appended claims.
What is claimed is:
I. waterproof package for a roll of strip material wound upon a core, said package com prisinga pair offdisclilie elements abutting the respective end faces of theroll and formed with axial collars withinwhich theprojecting end portions of the core are received, a pair of end caps mounted upon the respective'end portionsof said core and telescoping over the collars of the first-mentioned package elementthereon, and a peripheral wrapper around the roll, thema-rginal portions ofsaid wrapper folded over the ends of the roll onto the respective disc-like elements thereat, said package elements being united to each other in water-proof relation.
2. An end protect-or for strip material wound upon a core, said protector comprising a composite structure having a pair of axially aperturecl discs positionable against the end face of the rolled material and a sleeve in which the pro jectingend portion of the core is receivable; said The respective parts of the core-cap are sleeve having an end portion slit-ted and fanned radially outwardly, said sleeve extending through the axial aperture in one of said discs, the latter being bonded to each other with the fanned out portion of the sleeve confined therebetween, and a cap-like member mountable upon the projecting end portion of the core in telescoping relation with said sleeve, and bonded to the latter.
