The invention, however, is ahly longer than the shafts l2 and 15 so that the applicable to other uses. sprocket wheels carried by the shafts H and M An object of the invention is to provide eaare spaced much more widely apart than the 5 tremely simple mechanism and method which sprocket wheels carried by shafts l2 and I5. 5 is sturdy and inexpensive to manufacture and Thus, those springs which are carried by the link which eifectively crepes paper asit is fed through chains adjacent the shafts il and M are conthe machine. A further object is to provide a siderably stretched while the springs near the method and meanswhereby paper is longitudishafts l2 and it are contracted to a much greater m nally creped in an encurate and uniform manner. extent.

Each of the the individual Spaced rounds of p g 5 links of the chains is provided with an integral which g p t moistened P p and Uniformly inward extension strap ll which is perforated to contract ornarrow the small portion of h paper receive the hoolr end 22 of one of the springs ill engaged l the individual roundause Of the comprising spring mechanism C. action of the great munloer of convolutions or to The spring mechanism 0 consists of a number rings of the springs and because of the resiliency so oi? coil springs 23 each provided with hooks ll of the paper induced by the moistening, there is engaging the perforated straps ll of the linlr found to be no tearing of the paper but a unichains. The coil springs 23 are preferably of form contracting thereof throughout its entire equal length, but are stretched under the arwidth. There is no tendency for the paper to W rangement of the link chains shown. it will be slip between the springs, but, on the other hand, 55
the contracting of the paper is progressive and simultaneous with the contracting of the springs.
While I have described springs as being employed and prefer them because of their simple construction and inexpensive character, it will be understood that in place of the springs, individual ring mechanism may be employed together with other means for progressively bringing together the separate rings to narrow the paper. By employing springs, however, I find that a very uniform stretching occurs with uniform spacing of the individual rings so that excellent results are obtained. At the same time, should one of the springs become broken or set in an extended position, the ring can be readily removed and replaced at very slight expense. Thus, in the operation of the machine, should one of the operating ring structures become injured or inoperative, it is not necessary to throw away the entire spring belt, but repair or substitution can be made readily with respect to the one element at very slight cost. Further; should one of the springs be found to contract with less facility and in uniform relation to the others, this spring can be removed and replaced without affecting the remainder of the spring belt.
The mechanism is extremely simple, extreme- 1y easy to repair and maintained in operation, and accurate and effective in reducing the width of paper and creping it.
The foregoing detailed description has been given for clearness of understanding only, and no unnecessary limitations should be understood therefrom, but the appended claims should be construed as broadly as permissible, in view of the prior art.
I claim:
1. In creping apparatus, a frame, a pair of endless belts arranged one above the other, means carried by said frame for supporting said belts so that the inner portions of the belts are in adjacent relation and adapted to receive therebetween the paper strip to be creped. said belts each comprising separate coil springs which are stretched at one end of the frame and progressively contracted until they reach the other end of the frame, the springs of one belt being in staggered relation with respect to the springs of the other belt.
2. In creping apparatus, a frame, drive shafts mounted in said frame, sprocket wheels carried by the ends of said shafts, chains engaging the sprockets of said wheels, one chain being above the other at each side of the frame and the shafts at one end of the frame being longer than the shafts at the other end of the frame, coil springs carried by said chains being thus stretched at the end of the frame where the shafts are longer and being contracted toward the end of the frame where the shafts are shorter, the innermost portion of said springs being brought into adjacent relation and being adapted to receive therebetween a paper strip, and means for driving one of said shafts.
3. In creping apparatus, a frame, a pair of shafts at each end of the frame supported in superposed relation, the shafts at one end of the frame being longer than the shafts at the other end, sprocket wheels carried by said shafts, universal Joints in said shafts, endless chains engaging said sprockets and supported one over the other at each side of the frame, the links of said chains being equipped with spring-engaging projections, coil springs engaging said projections and extending across said frame so as to form a spring belt in which the coils are expanded at the end of the frame where the shafts are longer and relatively contracted at the end of the frame where the shafts are shorter, the springs of one belt being in staggered relation to the springs of the belt thereabove and the adjacent inner portions of said spring belts providing between them a tortuous path for receiving paper to be creped.
