2 Claims. l

The present invention relates to the art of textile finishing machinery and is primarily concerned with an attachment or accessory to be used with a Palmer Roll.

A Palmer Roll is a widely used and well understood machine for finishing textiles. In general, it comprises a large smooth surfaced drum which is maintained at an elevated temperature and which rotates about its axis. An endless blanket of felt or similar material moves in contact with the rotating drum throughout the greater portion of its circumference after which it leaves the surface of the drum at one place and returns at another adjacent thereto by passing over idling rollers. Cloth to be treated is dampened and fed in between the drum and is removed endlessly at the point where the blanket is separated from the drum. During its passage through the machine, the textile being treated is dried in contact with the polished surface of the drum and therefore leavesthe drum with one side thereof finished to a comparatively high gloss. The opposite side of the cloth, however (the side in contact with the blanket), has a dull surface, thereby resulting in what is known `as a two-sided effect.

One of the objects of the present invention is to provide a novel attachment for a Palmer Roll which enables the cloth being treated to beremoved from the machine with both sides thereof finished to substantially the same high gloss.

Another object is to provide a novel attachment for a Palmer Roll which removes the twosided effect from cloth treated by the Palmer Roll.

Still another object is to provide a novel attachment for a Palmer Roll which polishes the dull surface of textile material passing from the Palmer Roll.

Yet another object is to `accomplish all of the above in a simple manner, at low cost and without increasing the time of treatment.

Other objects and advantages will become apparent from the following description `of a preferred embodiment of my invention which is illustrated in the accompanying drawings.

In the drawings:

Fig. 1 is a side view of the portion of a Palmer Roll where the cloth being treated enters and leaves the machine, the attachment or accessory forming the subject matter of the present invention being shown mounted upon the Palmer Roll; and

Fig. 2 is a fractional front View of one side of the surface of the drum to the desired temperature. This drum has a ground and polished cylindrical surface l2 and an endless blanket I4 of felt or similar material in contact therewith. This blanket passes about idling rollers, not shown, and thence over an entrance roller IB where it is brought in contact with the drum face. From this point the blanket passes around.

15 the drum and leaves the drum around an exit yroller i8. The fabric to be treated, indicated by the numeral 20, passes inwardly with the blanket over the roller IG and thencearound the drum il? with one side thereof against the polished drum surface while the other side is supported by the blanket I4.

All of the above-described mechanism forms no part of the present invention, it comprising merely the essential elements of a standard and well known Palmer Roll. Ordinarily the fabric 2U being treated is removed from the surface of .the drum and separated from the blanket at the roller I8 in the reverse manner that the fabric enters the machine in contact with the blanket around the roller l', The result i5 that the surface of the cloth which was in contact with the drum has a comparatively high polish while the opposite surface which was in Contact with the blanket I4 is dull.

I prevent this effect by the use of an attachment. indicated generally by the numeral 22. This attachment comprises a bracket 24 at each side of the machine which has one end thereof journaled as at `2li to the `shaft 28 of the blanket take-olf roll I8. The opposite end of each of these brackets is provided with a hole 30 through which a stud 32 passes. These studs have their inner ends 34 threaded into tapped openings in a portion 3B of the Palmer Roll frame. The opposite or outward ends of the studs are threaded to adjusting nuts 38 which bear against the outer ends of coil springs lill. These springs surround the studs and press with their inner ends against the outer surface of the brackets 24.

At an intermediate point each bracket 24 carries a bearing block 42 which is journaled to the shaft of what I refer to as a polishing roll 44. This roll is free to rotate upon its axis and is urged against the smooth surface of the Palmer Roll drum With any desired pressure, depending upon the adjustment of nuts 38. The axle 48 upon which the roll 44 is mounted carries a small sprocket 4B connected to a sprocket 50 by a chain 52. The sprocket 59 is mounted at the end of the blanket take-off roll I8 so as to rotate therewith and the ratio of the sprockets 50 and 48 is such as to drive the roll 44 at a peripheral velocity different than the linear velocity of the blanket I4, preferably at a higher velocity. In other words, if the radius of roll I8 plus the thickness of the blanket I4 is approximately the same as the radius of the roll 44, then the sprocket 50 should be larger than the sprocket 48. 1t will be appreciated, of course, that the roll 44 may be of any convenient size, it being necessary merely to adjust the sizes of the sprockets 59 and 48 so as to give the roll 44 a peripheral velocity somewhat greater than the velocity of the blanket I4.

In using this attachment the cloth 2|] being treated is not brought out and separated from the drum I at the roll I8. Instead the blanket is separated at this point but the fabric being treated continues in contact with the drum I and passes cut around the roll 44. When the machine is in operation, therefore, the side of the cloth in contact with the drum ID receives a high polish during the major period of treatment. At the point where the cloth is separated from the blanket I4, that is, at the roll I8, the back surface of the cloth will have the dull nish, but this surface is brought in contact subsequently with the roll 44 which has a higher peripheral velocity than the velocity of movement of the cloth 28 and therefore the roll 44 slips relative to the cloth and gives the outer surface thereof a polishing action.

I have found that when cloth is treated in a Palmer Roll machine which has my accessory attached thereto that by proper adjustment of the nut 8S so as to urge the roll 44 against the back surface of the cloth with the appropriate amount of pressure, the cloth being treated will leave the machine with both surfaces thereof polished to substantially the same high gloss and in fact it is diicult by subsequent examination to determine which surface of the cloth was previously against the drum I0 during treatment.

It will be appreciated that variations may be made in my attachment without departing from the scope of the invention. As an example, by using take-up rollers which pull upon the cloth so as to remove it from the machine under tension, it is possible to get much the same effect by driving the roll 44 at a peripheral velocity less than that of the blanket. In either case, the roll 44 slips relative to the cloth being treated and therefore gives the polishing action.

Having described my invention, what I claim as new and useful and desire to secure by Letters Patent of the United States is:

l. Por a Palmer Roll machine having a rotating heated drum, a continuous blanket which lies against a substantial portion of the circumference of the drum and follows the rotation thereof, and

entering and exit rolls which maintain the blanket against the drum, the former feeding the blanket against the drum and the latter separating the blanket therefrom, the two leaving an exposed portion of drum surface not covered by the blanket wherein the material to be treated is introduced against the exposed portion of drum surface; an accessory for removing the two-sided effect from the material after passage through the machine comprising a smooth surfaced polishing roll disposed adjacent the exposed portion of the drum between the exit roll and the point of ymaterial entry, bracket means rotatably mounted upon the exit roll shaft for journaling the polishing roll-for rotation, means for resiliently urging the polishing roll toward the drum of the Palmer Roll in a position to nip the cloth emerging from the exit roll against the drum, and drive means for rotating the polishing roll in a direction opposite to that of the drum and at a higher peripheral velocity than the linear velocity of the cloth passing through the machine.

2. For a Palmer Roll machine having a rotated heated drum, a continuous blanket which lies against a substantial portion of the circumference of the drum and follows the rotation thereof, and entering and exit rolls which maintain the blanket against the drum, the former feeding the blanket against the drum and the latter separating the blanket therefrom, the two leaving an exposed portion of drum surface not covered by the blanket wherein the material to be treated is introduced against the exposed portion of the drum surface; an accessory for removing the two-sided effect from the material after passage through the machine comprising a smooth surfaced polishing roll disposed adjacent the exposed portion of the drum between the exit roll and the point of material entry, bracket means mounted on the Palmer Roll machine for journalling the polishing roll for rotation, means for resiliently urging the polishing roll toward the drum of the Palmer Roll in a position to nip the -`4`5 'cloth emerging from the exit roll against the drum, and drive means for rotating the polishing roll in a direction opposite to that of the drum and `at a higher peripheral velocity than the linear velocity of the cloth passing through the machine.
