2 Claims.

This invention relates to napping machines, and it is primarily an object of the invention to provide a machine of this kind provided with means whereby the cloth is napped on both sides with the use of a single napping element or roller.

It is also an object of the invention to provide for use in connection with a napping machine a device for reversing the cloth to be napped so that both sides of the cloth may be napped.

Another object of the inventionv is to provide a machine of this kind including an elongated napping roll together with means for passing the cloth to be napped over one end portion of the roll and then reversing the cloth and passing the same over the opposite end portion of the roll whereby both sides of the cloth are napped.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved napping machine whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein Figure 1 is a diagrammatic view in perspective illustrating features of a napping machine constructed in accordance with an embodiment of my invention;

Figure 2 is a diagrammatic view in side elevation of the assembly illustrated in Figure 1;

Figure 3 is a vertical sectional view taken substantially on the line 33 of Figure 2 looking in the direction of the arrow.

As disclosed in the accompanying drawings, I denotes side members of a napping machine and the lower portions of said members I at an end of the machine rotatably support, as at 2, a, mandrel 3 for a roll R of cloth to be treated by the napping cylinder or roller C. This cylinder or roller C, as herein disclosed, is rotatably supported, as at 4, between the central portions of the side members I.

Rotatably supported between the side members I closely adjacent to and at a point above the mandrel 3 of the applied roll R is a roller 5 over which passes and contacts from above the cloth strip S as it leaves the roll R.

Rotatably: supported between the side members I at opposite sides) of thevertical center of the cylinder or roller C-arethe rollers 6 and I in parallelism with each other and with the cylinder or roller C. These rollers 6 and 'Iare so positioned as to have their lower portions extend below the roller 5 hereinbefore referred to and said: rollers 6" and I are spaced apart a distance less than the diameter of the roller or cylinder 0 and preferably e'quidistantly spaced from the verticalcenter of said cylinder or roller C.

The cloth strip S as it passes over the roller 5, or more particularly an end portion thereof, extends below the roller 6 and extends upwardly therefrom and across and in contact with the top portion of the napping cylinder or roller C. This strip S then extends downwardly for contact from below with the second roller 1 and then extends upwardly and over a roller 8 supported upon the upper edges of the side members I at the end of the machine remote from the roll R. The travel of the cloth strip S between the rollers I and 8 is on an upward and outward incline and said strip S passes rearwardly over the roller 8 and is continued downwardly to pass under the roller 9 rotatably supported between the side members I at the upper portion thereof. This roller 9 is at a point below the roller 8 and, as herein disclosed, is to the same side of the cylinder or roller C as the roller 8. This roller 9 is also positioned directly below a vertically positioned turning frame F.

This frame F is firmly held as described in working position and the upper portion thereof is in the form of an inverted V with the arms In of such upper portion in right angular relation. The cloth strip S passes upwardly from the roller 9 and over one of the arms I0 and then across the frame and back over the second arm Ill. The cloth strip S then extends downwardly from this second arm ID of the frame F and under the roller 9 but at the opposite side of the roller 9 from the first mentioned portion of the strip passing under such roller. This returned portion of the strip S extends from the roller 9 upwardly toward the end of the machine carrying the roller 9. This strip passes over a roller II bridging the space between the side members I and rotatably supported by the upper edges of the side mem- 5O hers I. The strip S then extends downwardly and under the roller I2 rotatably supported between the outstanding bracket arms I4 carried by the adjacent ends of the side members I. This strip S is continued upwardly and over the roller l5 bridging the space between and rotatably mounted on the bracket arms l4 and the strip S extends downwardly from the roller l5 and under the mandrel 3 and then up over the roller 5 and under the roller 6. From the roller 6 the cloth strip is extended up over the cylinder or roller C and then under the roller 1. From the roller 1 the strip S extends upwardly and over the roller Hi from which the strip S is directed as desired.

It is believed to be obvious from the foregoing that the course of travel of the cloth strip S is such as to bring both surfaces or sides into proper contact or engagement with the napping cylinder or roller 0, and it is to be particularly pointed out that the frame F is so constructed as to assure the proper spacing of the portions of the strip S for travel over the cylinder or roller 0.

As the driving means for the napping cylinder or any of the other parts of the machine forms no part of the present invention a showing thereof is believed to be unnecessary.

From the foregoing-description it is thought to be obvious that a napping machine constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that my invention is susceptible of some change and modification without departing from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed.

I claim:

1. A napping machine having a napping roller over which a strip successively passes, the combination of a member for reversing the strip before the successive passage, said member comprising a vertically disposed frame, the upper portion of which is in the form on an inverted V, the upwardly inclined arms of the frame being in substantially right angular relation, and means for guiding the strip after it leaves the frame to pass over the roller in inverted relation thereto whereby the strip is successively treated on opposite sides thereof.

2. A napping machine having a napping roller 'over which a strip successively passes, the combination of means for reversing the strip before the successive passage, said means comprising a vertically disposed frame, the upper portion of which is in the form of an inverted V, the upwardly inclined arms of the frame being in substantially right angular relation, a guide roller supported below the frame and under which the strip travels as it moves to the frame and after it leaves the frame, and additional rollers coacting with the strip to guide the strip back to the napping roller in inverted relation thereto whereby the strip is successively treated on opposite sides thereof.

WILLIAM H. MERRIMAN.
