RIBBOZINE MACHINE T all whom it may concern:

Be it known that 1, CHARLES VVIEBKE, a

Specification of Letters Patent. Application filed. October 31, 1907.

citizen of the United States, residing at New- I ark, in the county of Essex and State of New Jersey, have invented a certain new and'useful Improvement in Ribbozine-hlachines, of which the following is a specification, reference being had therein to the accompanying drawings, forming part thereof.

My invention relates to textile machines in which textile material is sized, burnished, crimped, or otherwise treated by means of rollers, and it is described particularly as applied to a machine for manufacturing ribbozine, although it is applicable to machines for various other purposes.

The term ribbozine is used to designate an imitation of or substitute for ribbon which is made by sizing a bundle of threads and then pressing the thread out into a flat band which is then dried and burnished, and, in some instances, crimped.

In sizing the threads they are drawn through a bath of gum or other suitable size, and they are then passed between pressing rolls by which they are flattened into a band and the surplus size is removed. The material then passes directly to two heated rolls by which it is dried and burnished. From the burnishing rolls it passes directly to the corrugated crimping rolls.

It has been found in practice that when the several sets of rolls are driven at the same peripheral speed the operation of the machine is defective, owing to the fact that variations in the length of the material occur as a result of the several operations, so that the material is not maintained at the proper tension in its passage through the machine. The operation of the crimping rolls in particular results in shortening the material, while the drying of the threads also results in shrinkage.

The object of the present invention is to so organize a machine of the character described as to avoid either unnecessary tension or the accumulation of slack material between the several sets of rolls, and to this end the invention consists, broadly speaking,

in a machine in which the several sets of rolls are driven at different peripheral speeds to compensate for shrinkage in the material and for other variable conditions of working.

More specifically, the invention comprises a machine of the character referred to m which the absolute and relative speeds of the Patented April 28, 19O8."

Serial No. 400,079.

several sets of rolls are adjustable to adapt the machine to various materials and various conditions of operation.

I will now describe the embodiment of my invention illustrated in the accompanying drawings, and will thereafter point out my invention in claims.

In the drawings Figure 1 is a side elevation of a ribbozine machine embodying the invention. Fig. 2 is a longitudinal section of the machine, with the driving mechanism omitted. Fig. 3 is a transverse section showing in detail the burnishing rolls and adjacent parts.

In the machine of thedrawings the sizing material is contained in a tank 1, through which the material 2 is drawn about suitable guides, as shown in Fig. 2. The material then passes to the pressing rolls 3 and 4. The roll 3 is made of rubber, while the roll 4 is of metal, andthese rolls act to flatten the material into a band and to press out all surplus size. From the pressing rolls the material passes directly to the burnishing rolls 5, which are of metal. The burnishing rolls are heated by a gas burner 6 in a manner common in mac they act both to dry the material, by heating it and pressing out the surplus moisture, and to burnish or smooth it so as to impart a glossy and pleasing appearance. From the burnishing rolls the material passes directly to the crimping rolls 7, which are corrugated and heated and operate in the ordinary man ner to crimp the material.

The lower roll ofeach pair is provided with a gear wheel 8 meshing with a pinion 9 fixed to a transverse shaft 10 journaled in the frame of the machine. Eachshaft 10 carries a bevel gear 11 which engages a pinion 12 on a longitudinal shaft 13. The shafts 13 are journaled in line with each other in uprights 14 on the frame of the machine. Each shaft 13 carries a grooved conical pulley 15, and the pulleys 15 are connected, by belts 16, with corresponding conical pulleys 17 fixed to a drive-shaft 18. The shaft 18 is actuated by a pulley 19 connected by a belt with a suitable source of power.

The mechanism above described serves to actuate the several sets of rolls at speeds varying according to the positions of the several belts 16 on their respective pulleys. In the. arrangement shown in the drawings the belts are so placed that the burnishing rolls rotate a little faster than the pressing rolls,

limes of this character, and

so that they maintain the material under tension and have a rubbing action by Which the burnishing eflect is augmented. The crimping rolls are operated somewhat slower than the burnishing rolls, to compensate both for the crimping action and for the shrinkage which occurs in the material as it dries. be apparent that these several speeds may be varied both relatively and absolutely by changing the positions of the several belts, so that the machine may be adjusted to operate properly under Widely Varying conditions.

It is obvious that various modifications I comprising a pair crimping rolls more slowly than the burnishing rolls to compensate for the shortening of the material.

2. A ribbozine machine comprising a pair 3. A ribbozine machine comprising means for sizing the ribbozine, a pair of pressing rolls for removing the surplus size and flathe material, a pair of heated buring the rolls, able to vary independently the several sets of rolls.

In testimony whereof I afliX my signature in presence of two Witnesses.

CHARLES WIEBKE.
