firma/vers Patented Oct. 23, 1945 ,UNITED .STATES PATENT OFFICE original application VNox/miser 13,1941, seria-lise. 418,939, now Patent No. 2,321,010, dated-June 8,19435. Divided and this 1943, Seriallm 486,515
` nomme. (ci. `1er-61) Mylinvention relates to `machines for handling flat, open, woven or knitted fabrics after processing and nishing and is `particularly useful in cbrmcttion with flat knitted rayons which because ,of their (structure are veasily pulled out `of shape and so require special care to prevent distortion.
mreuniformly treated if the cloth is in tubular form so that it may beuniformly spread to width While allowed to contract lengthwise, then `processing and finishing such fabric while in tubular form and then restoring the fabric to open form prior to nal winding.
The object of the invention is to provide rotary cutting means adjacent and prior to the nal rolling up of thefabric for removal of the sewn edge and thereby restoring the material to open form.
My invention" is illustrated in the annexed drawing, in which Fig. l is a top viewof my improved rotary cutter, the top of the housing thereof being removed;
. Ibave found thatsuch nat `knitted fabrics may Figs. 2 and 3 are sections taken along lines 2 2 and 3-3 of Fig. 1 respectively; and
Fig. 4 is a side view of the apparatus in place between the finishing and final rolling operations.
The fabric after-doubling, trimming and sewing issubjected in fiat form to the usual nishing operations such as dyeing, drying, shrinking,
l stretching, steaming and finally pressing. Durtene`d condition and travels between calendering rollers 54, 55 (Fig. 4) and drops upon moving belt conveyor 62 which carries the material to cutting machine 58 (Figs. 1, 2', 3).
After traveling a short distance on belt 62 the seamed edgei'l of the fabric comes in contact with cutter guide 56 (Figs. 1, 2, 3). This guide leads the edge into operative position with cutter Wheel 6Dat a point slightly above the planeof the moving conveyor belt and acts to position and support the fabric while the seamed edge is trimmed off by the cutter.
, The cutting machine 58 consists of a housing 59 containing a cutter wheel 60 mounted on a rotating shaft 6|. The bottom 63 of said housing application May( 11,
(Figs. 2, 3) consists .of a hollow casting having a dat underpart 64 anda convex upper surface 65 with a recess 66 intermediate the upper and lower portions of the casting. In trimming off the seamed edge of the material the upper convex surface acts as a cutting table, the edge 61 of wheelbeing .arranged Yto cut the material and rotate in slot 6'8 and'recess 66 in the bottom -64 of housing 58 (Fig. 3), is restored to open form.
Next the material may `drop back onto moving conveyor belt 62 (Figs. l, 2) which transports it to wind-up mandrel 'I2 (Fig. 4) upon which the nished fabric is wound.
In disposing of the waste strip of goods 69 (Fig.
l) resulting from cutting away the seamed edge,
it may be first passed beneath a guide associated with thecutter and then under a driven roll 13 positioned behind the wind-up mandrel T2 before permitting the strip to drop into an appropriate waste receptacle (not shown). e
The flat fabric, automatically formed into tubular shape, is treated in this shape and then restored to fiat condition continuously and auto- Y matically with consequent speed, accuracy and uniformity of treatment and uniform quality in the product.
This application is a division of my co-pending application Serial No. 418,939, filed November 13, 1941, for Method and apparatus for treating fabries, now Patent No. 2,321,010 of June 8, 1943.
I claim:
1. Apparatus for severing an edge of a traveling fabric tube including a` spreader bar engaging an edge of said tube and positioning and tensioning said edge for cutting, cutter means associated therewith and severing said edge, a driven mandrel winding up the severed fabric, and spreader means for disposing of the severed edge.

Apparatus for severing an edge of a traveling fabric tube including a spreader bar engaging an edge of said tube and positioning and tensioning said edge for cutting, cutter means associated therewith and severing said edge, a moving belt for transporting said fabric, a driven mandrel winding up said severed fabric and means maintaining the severed edge against lateral displacement consisting of an extension of the spreader, said extension passingover the severed edge as said edge leaves the cutter and roll means adjacent the wind-up mandrel.
3. Apparatus for severing an edge of a traveling fabric tube including a spreader bar engaging an edge of said tube and positioning and tension- By this operation the fabric l traveling fabric tube including a spreader bar xed in position with relation to said apparatus and engaging an edge of said tube and positioning and tensioning said edge for cutting, cutter means associated therewith and severing said edge.
5. Apparatus for severing an edge of a traveling fabric tube including a spreader bar engaging an edge of said tube and positioning and tensioning said edge for cutting, cutter means associated therewith and severing said edge, means for varying the location of the cutter means in a direction transverse to the fabric and a driven mandrel winding up the severed fabric.
6. Apparatus for severing'a sewn edge of a traveling fabric tube including a spreader bar fixed in position with relation to said apparatus and engaging an edge of said tube and positioning and tensioning said edge for cutting, cutter means associated therewith and severing said edge, and means for varying the location of the cutter. means in a direction transverse to the fabric.
- 7. A machine for handling textile fabric comprising a pair of driving rolls between which flattened tubular fabric passes, means following said driving rolls for slitting said fabric adjacent one edge of the attened tube and severing said edge including a guide within said attened tubular fabric.
8. A machine for handling fabric comprising means for passing attened tubular fabric continuously through the machine and means for tensioning oney edge of said fabric without tensioning the other edge, and cutting a predetermined narrow strip of fabric from said tensioned edge of the flattened tube.
9. Apparatus for treating traveling tubular textile fabric comprising means for spreading and flattening said fabric, finishing rolls for pressing the fabric, means for Winding the fabric and means between the finishing rolls and winding means for cutting a strip of fabric of predetermined width from one edge of the flattened fabric tube.
10. The method of finishing and handling tubular fabric which comprises spreading thev fabric in attened form and passing it between finishing rolls, tensioning one edge of the flattened tube and cutting a predetermined narrow strip of fabric from said tensioned edge, and Winding up.
