" jigsaw 19 7-31- This invention has for its object to provide a method and means whereby decorative effects can be applied to textile fabrics in a simple and relatively inexpensive manner.

According to the invention decorative patterns are imparted to textile materials in a continuous manner from placed side by side or spaced apart and brought into contact with the fabric, so as to apply the design where required.

The transfers may be used inthe form of reels, from which the strips are guided to means for'applying heat and pressure, through which means they pass in contact with the textile material. The reels may be mounted on spindles or pins on which they can turn to allow the strips to come off freely, with means for spacing the reels if necessary, and if desired with guides for the strips passing to where they make contact with the textile material. Alternatively the reels may rest in a trough or channel in which they can turn as the strips are wound off, in which case there may be slots in a side wall of the trough @Patent or channel to guide the strips leaving the reels. If desired two parallel rows of reels may be used, in which case two adjacent transfer strips may be made to overlap 'while in contact with the textile material.

The application of heat and pressure may be effected by means of rollers between which the textile material and the transfer strips pass, one or both of the rollers being heated, e.g. by means of steam or electricity. Where a double thickness of textile material is used, as in the case of knitted materials in tubular form, it may be possible to apply transfers simultaneously on both sides of the material, using two heated rollers. Means may be provided for adjusting the pressure between the rollers. Alternatively, a roller may be used for pressing the materials against a heated table.

The invention is applicable to knitted and woven fabrics, and provides lasting decorative effects much more the arrow A in machine.

The machine 1 is driven by an electric motor 2 through a reduction gear 3 with a pulley 4 from which a belt 2 9 ,8 5 Tia-tented Dec. 11, I959 drives a pulley ,5 on a shaft-6. -A pulley 611 on the shaft6 drives a pulley -7 onone end of azheated roller 15 which at its-other end carries a gear wheel 41 driving a wheel 42 on another heated roller 16. A pulley 8.on .theshaft 6drives a pulley 9 -on --one of a pair offeltcovered rollers 1-1, 12, which have a peripheral speed slightly higher :than that of the heated rollers 15, .16.

:A ,pulley 10 on the shaft 6 drives asimilar pair of felt covered trollers 13, 14 at'the back of the machine through 'a.pulley'10a.

of transfers pass to the heated rollers 15, 16 on either side of the fabric 43, further guide rollers 21, 22 and 23, 24 being provided to ensure that the transfers are in contact with the rollers 15, 16 over a large part of the periphery thereof, so as to be heated before touching the fabric end to be drawn away from the fabric as it leaves the nip. The transfer strips come from reels 25, 26 and 27, 28 arranged in staggered relationship, and after passing over the rollers 21, 24 are drawn away by the felt rollers 11, 12, and 13, 14 which keep the strips in tension owing to their speeds being higher than that of the rollers 15, 16.

The reels 25-28 are of continuous paper strips bearing designs in one or more colours in thermoplastic or thermosetting inks which are softened by the heat from the rollers 15, 16 and transferred to the outer surfaces of the double layer of cloth 43. The imprint on the cloth sets as it cools on leaving the rollers and is then quite fast.

The heated rollers 15, 16 are hollow, with tubular ends running in bearings 37, 38 and 39, 40. The bearings 37-40 are mounted in slides 35, 36, the bearings 37, 38 of the roller 15 being adjustable by means of screws 47 which bear on the bearings through springs 48, for the purpose of adjusting the pressure between the rollers. Passing through the rollers 15, 16 are rods 49 supported at their ends by brackets 50 in the case of roller 15 and brackets 51 in the case of roller 16. Each rod 49 carries an assembly of electric heating elements 52 to which current is supplied by leads 53, the rods 49 being stationary. The fabric is guided between the rollers 15, 16 by guides 54.

The transfer reels 25, 26 at the front of the machine are arranged in two rows in staggered relationship. Each reel is carried by two pins 55 on metal plugs 56 inserted in the ends of the reel core. The pins 55 enter oblique slots 57 in metal strips 58, the ends of which have slots 59 open at the bottom to fit over threaded rods 60 extending along the machine. The strips 58 are located by nuts 61 threaded on to the rods 60. The reels 27, 28 at the back of the machine are similarly arranged. Any number of reels may be used, depending on the widths of the transfer strips and the fabric. In the case of a single layer of fabric the reels at the back of the machine may be dispensed with. The transfer strips may be spaced apart if necessary, or may be close together or may overlap. With this arrangement exhausted reels can be replaced very quickly, and the machine may if necessary be stopped for the short period required to change a reel without ill effects.

What I claim is:

1. A machine for imparting decorative patterns to textile materials, comprising a pair of rollers, means for heating the rollers, means for supporting a roll of fabric above the rollers, and for guiding the fabric to the nip between the rollers, means for supporting a plurality of reels of expendable transfer strips in front of and behind the rollers, the reels being arranged in rows in staggered relationship at both the front and the back of the rollers, such reels supporting means comprising pairs of rods parallel to the rollers, adjustable spacing means on the rods, and pairs of strips each having slots to fit on the rods between the spacing means and oblique slots for receiving pins at the ends of transfer reels, means forguid ing the transfer strips side by side from the reels at the back of the rollers to the rear roller and from the reels at the front of the rollers to the front roller, each strip making contact with the roller over a large part of the surface thereof and the fabric passing between the strips surrounding the two rollers and making contact with the strips at the nip between the rollers, means for driving the rollers, and means for applying pressure to the rollers. 7

2. A machine as claimed in claim 1, and having pairs of felt-covered rollers beneath the heated rollers, means for driving the felt-covered rollers at a peripheral speed exceeding that of the heated rollers, and means for guiding the transfer strips from the heated rollers to the felt-covered rollers.
