MACHINE FOR UNFOLIDING AND ROLLING CLOTH.

To all whom z't may concern.'

Beit known that I, BENJAMIN l/VEINBER`- GER, a citizen of the United States, residing at the city of St.Louis and State of Missouri, have invented a new and useful Machine for Unfolding and Rolling Clot-ln'of which the following is a specification.

This invention relates to machines for unfolding and rolling cloth.

At the present time various kinds of cloth are folded longitudinally and rolled or reeled upon boards to provide the bolts, inv

which form the cloth is distributed tothe dealers and to garment manufacturers.

My invention relates to mechanism for unfolding the cloth as it is removed from the bolt and rolling the cloth upon a roll to enable the cloth to be cut into proper lengths rapidly and with facility.

.lhe object of the invention is to provide a machine of the character mentioned, comprising a revoluble support for the roll or bolt of cloth, in combinationwith a roll adapted to have one end of the cloth connected thereto, mechanism for revolving the roll, a triangular element between the roll and the bolt of cloth over which the cloth is drawn and unfolded as it passes toward the roll, and tensioning devices for the cloth between the roll and the unfolding device. l

In the accompanying drawings, in whicha preferred embodiment of the invention is illustrated, e

Figure l is an end elevation of the machine.

Fig. 2 is a side elevation looking toward the unfolding device. e

Fig. 3 is a view illustrating a longitudinal guiding slot in the roll for guiding the knife whenV the cloth is cut in lengths. l

Fig. 4 is a similar view illustrating an oblique guiding slot in the roll for guiding the knife in cutting thev cloth obliquely.

Fig. 5 is a detailedtview illustrating a clamp which may be employed for connecting one of the ends of the cloth to the roll.

Fig. 6 is a perspective view illustrating in detail a part of the guide for the cloth as the cloth passes toward the unfolding device.

The machine illustrated comprises a frame composed of a stationary upright 1 and an adjustable upright 2 movabletoward and away from the upright l. The upright 2 maybe held inconnection with the supporting base by a clamping Vbolt 3 passing Specification of Letters Patent.

through an angular extension of the upright 2 and through a slot in the supporting base. The uprights 1 and 2 constitute supports for upholding the bolt of cloth which is to be unfolded and rolled. Y

The device for upholding the bolt of cloth includes preferably a metallic frame 4which may be constructed of small rods or spring wire as shown and provided with extensions adapted to seat in bearingsin the uprights 1 and 2, as will be understood by referencev to Fig. 1. rThe frame 4 may be easily inserted in the bolt of cloth by first removing therefrom the usual board upon which the cloth is Wound, and inserting the frame 4 in the space previously occupied by theV board. After the bolt of cloth has thus Vbeen placed upon the frame 4, the latter may be mounted in the bearings in the uprights 1l and 2 kand the free end of the cloth passed upwardly between guides below the unfolding device. rl`he guides for the cloth comprise two members 5. One end of each of the members 5 issupported by the upright l and the opposite ends thereof are ymounted. in a support 6 in which they are retained in spaced relation by a removable key 7 seating in the slot in which the members 5 extend.

By -reference to Fig. l, it will be observed that the support 6 is spaced from the upright 2, thus permitting the latter to be moved to different adjustments asrequired to accommodate and support bolts of cloth of different widths.

The unfolding device includes a triangu' larl guide 8 secured` to a supporting frame `9 and extending obliquely downwardly there.- from toward the guides 5, so that as the cloth is drawn between the guides one fold of the cloth will pass at one side of the guide 8 and the other fold of the cloth will` have illustrated a motor 12 driving a belt 13 passing over a pulley 14 in connection with the-roll 10. The end of the cloth which is drawn over the upper horizontal edge of the guide 8 is secured in connection with the roll 10 by releasable clamps l15, so that as the roll turned the cloth will be .wonndmlvinglthe actuating roll to draw the cloth thereon.

1n Aorder tol prevent Ybuckling of the cloth,

I provide a series'of tensioning guiding rrods 16 supported between the roll 10 andthe un-Y folding guide 8, and between which the end oftheeloth ispassed before it is connected. to 'the' roll'. Will be drawn between the rods 16 thus holding the cloth straight and maintaining it at proper tension.V

transversely :While on the roll andrto constitute @a guide-for the-knifef or cutting imple- ;ment, the roll is formed Witha longitudinal ser/vevfasa guide )for thelmife.

lSince-the :roll 10 isquitelarge and the cloth is Wound closely thereon, the variation inthe rlength ofthe layers of cloth is sovery slight that it is immaterial.y 1n practice, "therefore, the -roll- =is utilized `rto vplace the 'cloth in layers and since ythe7 :areso nearly of uniform length they are-infact used las I measured layers. v

vFromfthe foregoing description,it Willbe readily understood lthat the bolt is placed Within vthesupporting frame with -the fold of f the; clothy directly below the extremity of the -triangular guide S and Ithat thee'nol-v o'fthecloth is-passedoverfthe horizontal 11p-'- peredgeof theguide and thence 'between the rodsI 19 and Vto the roll, to 4which" the clothiis connected. Rotation of theroll vin the Vdirection of the arrow `in YFig.v L1 -Will- Wind the fcloth thereon, While the devices between-therolland'the bolt of cloth `serve first to unfold the cloth, and-then to give it the iproper tension preparatory' to being cutinto measured lengths as determined by theslots Ainl-the roll, or otherwise.

It Will-be apparent that many of the el'el cl-aimfand desire to secure by Letters Patent iscl.
