PAPER MACHINE N Inventor A iiorneys Patented Oct. 4, 1938 UNITED STTE eATEnT' OFFICE 1 Claim.

This invention appertains to new and useful improvements in paper machines and more particularly to an auxiliary rope carrier for paper machine driers. In paper machines. a carrier is employed to carry a narrow strip of paper over the paper machine driers. Oftentimes in carrying thestrip paper over the driers, the paper will break on the driers or drop out of the ropes and wrap around the driers forming a wad of wet paper. When this Wet wad of paper forms underthe ropes running on the conventionally formed driers, the ropes are generally displaced from the grooves of the driers and result in breaking of the ropes or tangling ofthe same. This causes a shut down of the driers and theinactivity of an entire paper machine before the ropes can be replaced.

The principal object of the present invention is to provide an auxiliary rope grooveway for each of the driers so that in the event the ropes become displaced they will be caught by the auxiliary grooveways.

Other important objects and advantages of the invention will become apparent to the reader of the following specification.

In the drawings:

Figure 1 represents a diagrammatic view show! ing the rope arrangement of a conventional paper machine.

Figure 2 is an end elevational view of one of the driers.

Figure 3 is an enlarged fragmentary detailed sectional view on the line 33 of Figure 2.

Figure 4 is a fragmentary inside elevational view of the auxiliary structure.

Referring to the drawings wherein like numerals designate like parts, it can be seen in Figure 1, that numerals 56 represent the lower and upper driers over which the pair of ropes travel. The outside rope is denoted by numeral 1 while the inside rope is denotedby numeral 8. Numeral 9 generally refers to a press in which numeral i is the guide roll. Numeral H represents the receiving roll. In the conventional paper machine the ropes 1-8 are carried in grooves on the front ends of the driers. These ropes travel close together except where they are made to approach each other as at the press 9 so as to grip the end of the tail of paper placed between them.

Assuming in Figure 3 that numeral represents one of the lower driers, it can be seen that the drier has the front end wall i2 and the extending peripheral portion 2| beyond this end wall. The cylindrical portion of the drier is provided with the internal end flange M. It can be seen that the conventional drier has the grooveway l5 therein in whichthe ropes l-8 are trained.

The structure forming the present invention is generally referred to by numeral it andconsists of an annulus ll divided into a multiplicity of sections a. Each of these sections a has a lug l8 extending inwardly therefrom and apertured to receive an elongated machine screw l9 which also extends through the end wall I2 and threads into the aforementioned flange i l.

The annulus I1 is provided with the circumferentially, extending outstanding flange 2%] which extends outwardly somewhat of the flange 2| of the conventional drier structure, so that in the event the ropes 'l--8 step out of the grooveway they are caught by the annulus ll.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

Having described the invention, what is claimed as new is:

An attachment for the drums of paper making machines of the type having rope grooves, said attachment consisting of an arcuate plate adapted to be secured to the rope groove end of a drum and having at its outer edge, an outwardly extending flange in spaced relation to the adjacent end of the drum and projecting in a direction radially with respect to the drum beyond the periphery of the drum to catch a rope displaced from the rope groove of the drum.
