The present invention relates to materialunrolling attachment for nap-raising machines and has for an object to provide a device constructed and arranged for incorporation in a nap-raising machine for knit goods or other nap-containing fabrics which: will act to; stretch andsmooth the material preparatory to the delivery of the ma-v terial to the feed rolls andfito. the nap-raising .In nap-raising,.machines, as presentlycon structed and used two attendants are required, one to each side of the, machine constantly engaged in unrolling the knitted materialqasit isbeing fed-into the machine. Sweaters'and: other 7-1 knit goods are ordinarily-originally fabricated in; a several body andsleevelengths knit inv one con tinuous piece to form. a stripe. The 'stripel-has natural rolled longitudinal edges.

The

' feed rollers l4 andlS pull the material'longitudinally into the napping machine over the tables and between the belts-andpre'ssure plates. Before starting theoperation the carriages are adjusted by energizing the motor 3| so that the belts H and I! may be moved to correct position towards or away from one another to accommodate the width of the stripe about to be fed. When this adjustment has been effected the limit switches 32 and 33 ale-energize the motor 3| either at the narrowest or widest limits permissible by the width of machine.

The main motor 46 is thenenergized to drive the belts and feed rollers as well as the napping brush and the stripe will thereupon move longitudinally into the machine and at the same time be subjected to transverse stretching movements of the belts IT and H which. cooperating with their pressure plates will unroll the side edge Y portions of the stripe and stretch and smooth the stripe so as to place it in most favorable conhundred per cent of the napping of the trans- I verse dimension chine.

The rock frames 51 pivotally carrying the pressure plates may be limited in the downward movements of the pressure plates by complemental stops ill, H. The springs 63 are in effect an adjustable counter balance for the weight of the plates carried by the rock frames 51. The plates impose their weights upon the material both by a vertical sliding movement in the rock frames 51 and also by the angular movement of the rock frames 51 about the pivots 58.

Although I have disclosed herein the best form of the invention known to me at this time, I reserve the right to all such modifications and changes as may come withinthe scope of the following claims.

What I claim is:

2. In a material unrolling attachment for napraising machines, the combination with the usual feed rollers, of a pair of endless belts positioned to engage the material at its underside forwardly of the feed rollers and disposed to move in relatively opposite directions transversely of the path of the material in moving to the feed rollers, and means disposed above said belts for exerting pressure downwardly upon the material to urge such material against the belts. f I

riages movably mounted on said frame, means for moving said carriages together or apart, movto drive said stretchers, said gearing slidable relatively along said shaftand having drive gears fixed to rotate with said shaft.

10. In a material unrolling device, an end-' less belt positioned to receive the material, drive means to move said belt, a pressure plate above the belt and means for suspending the plate for vertical sliding movement to enable its weight to be imposed at least partially upon the material engaged with said belt. I

11. In a material unrolling device, an endless belt adapted to receive the material, drive means to move the belt, a pressure plate mounted for vertically adjustable movement above said belt, and means to adjust the lower limit of movement of said plate. I
