Application filed September 15, 1910. Serial No. 582,276.
Specification of Letters Patent.
. Patented To all whom it may concern:
Be it known that'I, CHARLES FRA GIs JENKINS, citizen of the United States,-residing 'at Washington, Districtof Columbia, have invented certain new and useful Improvements in Paper-Tube Machinery, of
g whichthe following isa specification.
This invention relates to improvements in tubewinders, and has for its main object a more effective grip on the paper by the feeding belts. 1
Tubewinders are usually made with a sta- 'tionary nonrotat-ing mandrel and one or more driving belts lapped around this mandrel, the paper tube being formed between the two. The feeding traction on the paper, to advance it, is the difference in the amount a of friction between the stationary surface of the mandrel, which resists, and which is kept as smooth as possible to make the re-.
enough to pull the paper along but overcome' the drag of the paper through the gluing device. With thin paper this difierence falls to almost nothing, under the best conditions, so that extreme care must be maintained to keep'the machine operative.
The object of this invention is to increase this difference of resistance, i. e., the resistance to movement: by the paper in contact with the mandrel, and the tractive force of the belt on the larger diameter of the outside .of the tube, by decreasing the amount of frictional resistance on the mandrel, and is accomplished by providing a grip on the inside of the paper tube. This is effected by arranging one-or more rows of balls spirally around the mandrel so that the tops of the b ll s and a li tle g e h n t e s f f 1a mandrel B,
' paper. slstance ward with a force :pieces if it is held the mandrel, with means for returning the alls from the end of the raceway back to the beginning of it, as shown in the draw ings, in which- Feb. It, ran.
Figure 1 is a top view of the common form of tubewinder; Fig. 2 a side View of a section of the mandrel underone or both of the winding belts, and concealed thereby; and Fig. 3 avertical section of the same portion of the mandrel. I
In the figures, A is'a supporting frame for around which belts C are wrapped.
D and D are balls in two channels or race ways arranged spirally around the mandrel,
beginningfat the underside of the mandrel as at-D and D and ending on to of the mandrel as at. D and D after ma ing one I and one-half turns around the mandrel. At
this point the balls drop through the mandrel wall into the upper end of an inclined raceway E by means'of which they are returned to the beginningof the spiral.
As the top 'of the balls are higher than the surface of the mandrel and lie under the belt it is obvious that the belt will bear hardest on the balls, andthat paper running between the balls and the belt will be firmly gripped between them and driven forward, around the mandrel, with a tractionamounting practically to a positive grip on the on the inside of. the formed and forming tube is greatly reduced, and at the sametime the tractive eflect of the belts is multiplied, so that the paper isdriven for from tlfe mandrel. The method of laying the paper on the mandrel, as well as the method of form the paper tube, are so familiar. to those skilled in the art that an illustration of just how paper is wound on these'mandrels 1s believed unnecessary In other words, the frictional resufficient to. tear it in i at some point distant I gluing up the several layers'to and it is therefore ered mechanical equivalents,
and the word balls only is therefore used.
What I claim, is-
5 1. Inv a tube-winder,
spiral raceway therein, rolling 2. In a tube-winder,
. spiral raceway therein, 1 balls in said raceway. 3. In a tube-winder,
a mandrel having a and. a plurality of members in said raceway.
a mandrel having a and a plurality of a mandrel having a balls insaid raceway, Ithe balls extending slightly beyond the surspiral raceway therein, and a plurality of the exposed portion of face of the mandrel. 15 In testimony whereof I have aflixed my signature in presence of two witnesses.
