Divided and this application Decemher 2:, 1939, Serial No. notes 2 Claims. (01. sis-cs This invention relates to apparatus for winding iabrlc supplied either in short or 7 continuous lengths.

An object of this invention is to provide means whereby fabric may be wound on a mandrel,

severed at selected points and winding begun on Fig. 2 is a sectional view of a manually operated wind-up and arbor changing device;

Fig. 3 shows the apparatus of Fig. 2 immediateiv after the material has been out;

Fig. 4 is a sectional view of an automatically operated wind-up and arbor changing device;

Fig. 5 shows the apparatus of Fig. 4 immediately after the material has been cut; and

Fig. 6 is a plan view of the apparatus of Fig. 4.

The material to be wound passes partly around a driven roller 88 after which it is wound on mandrel I18. The latter has pintles resting in inclined grooves 201 of an extension bracket "While the winding is in progress the fabric on the mandrel bears against driven roller .86 which serves to rotate the mandrel and overlying fabric. Asthe body of fabric increases in size the plntles of the mandrel move along grooves ill and away from roller 86 (Figs. 2 and 4) Recesses 209 in the top of bracket 208 receive the pintles of an unfilled mandrel III which is held in readiness to be placed in position to receive the fabric when mandrel I'll is removed (Fig. 2). There are downwardly extending grooves III in the brackets 20! which at the bottom communicate with grooves 201.

When mandrel "8 has been filled it is moved along the brackets 208 to extensions I00 at the outer ends of grooves 201, thus taking roll 28 out of contact with driven roller 88 and away from the receiving position. The new mandrel Zlil is then lifted from the notches 209 and lnsertedin the upper ends of grooves 2| l. Mandrel 2M thereupon slides down grooves 2H and into engagement with roller 88. The material may now be severed by a cutter of the type shown in United States Letters Patent 1,746,476. In using a cutter of this sort fabric is permitted to accumulate between roll I! and roller 88 and to drop downward until it lies over cutter bar II I. The operator then moves cutter Ilfl across the cutter bar severing the material (Fig. 3) after which the end of the following strip of material is thrown over the new mandrel III which immediately begins to wind the fabric being delivered by roll I6. The operator then removes roll 26 from the machine. I

A means may be provided for dropping the new mandrel 2Ill automatically into operative position when the filled mandrel llt is removed. A suitable construction lot this purpose is illustrated in Figs. 4 to 6, inclusive. In this embodiment when mandrel I'll is shifted outwardly alone grooves 201 its plntles fall into sockets m on rocker arms 2 pivoted at 403 to brackets 208. The weight of the mandrel depresses arms 2 against tension springs tilt whichconnect extensions llli on arms tilt. with brackets 208. Jihe engagement of stop lugs 406 with the bottoms of brackets 20! arrests the downward movement of sockets llll and holds the filled mandrel lll in a convenient position for removal from the machine. Latch rods llll extend from extensions 405 along'the brackets 208 and pass through guides 408 on the ,inner parts of the brackets into position across auxiliary grooves ill when arms 402 are held in upward position by springs 404 as illustrated in Fig. l. I

While mandrel m is being filled replacement mandrel MI! is located in grooves ill resting on the ends of latch rods 601 (Fig. 4) The shifting of filled mandrel in into sockets till retracts latch rods m and automatically drops the replacement mandrel Iil into operative position. Then the fabric bout, the replacement mandrel started and the filled mandrel removed from the machine. 3

Our invention may also be used advantageously with fabric made up of a series of short lengths of fabric the ends of which have been fastened together. In such cases the operator employs the cutter to sever the fabric lengths at the points where they have been fastened together. When short lengths of fabric are used the cutter may not be needed.

By use of applicants invention the operator may remove the filled mandrel, sever the fabric and start winding it on the replacement man- .drel without stopping the machine. Applicants Moreover, if a fabric steaming or finishing machine must be stopped when the filled mandrel is removed the portions of fabric in the finisher will be subjected to a more prolonged steaming and stretching than the fabric which has passed through the finisher on its way to the wind-up. This causes variations in the width of the end portions of the fabric and frequently requires cutting off such end portions with resulting loss of fabric. Howeverby use of our wind-up ap- 1. In a fabric winding machine having a drive roller and a mandrel on which the fabric is wound, the improvement consisting of inclined guideways for said mandrel leading away from said drive roller and holding the mandrel in operative position therewith 'at a given point as the mandrel becomes filled, and communicating guideways extending upwardly from their point of Junction with said guideways and permitting a replacement mandrel to drop into operative position after removal of the filled mandrel.

2. A machine as set forth in claim 1 having latch means associated with the communicating guideways retaining the replacement mandrel therein and latch releasing means actuated by withdrawal of the mandrel from operative relationship to the drive roller.
