UNITED STATES PETER J. CHRISTMAN, J 3., OF GREEN BAY, WISCONSIN.
APPARATUS FOR MAKING STRETGHABLE PAPER.
Application filed May 26, 1925. Serial No. 33,060.
To all whom it may concern:
- Be it known that I, PETER J. OHRISTMAN, J12, citizen of the United States, residing at Green Bay, in the county of Brown and State of lVisconsin, have invented certain new and useful Improvements in Apparatus for Making stretchable Paper; and I do hereby declare the following to be a full,
clear, and exact description of the invention,.
such as will enable others skilled in the art to which it appertains to make and use the same. I
This invention relates to an improved apparatus for the creping of paper. The particular object being to provide an apparatus by which the use of water and what is termed in the trade doctor blade becomes 1111118065"? sary, that is the apparatus herein described and claimed produces a stretchable paper without moistening a web by passing it through a bath of water as now the common practice in the art.
In the drawings:
Fig. 1 illustrates a view of the apparatus by which the creping of the paper is accomplished, showing the built up pinch rolls, guide rolls, and belts in assembled relation to each other, as the paper passes therebetween.
Fig. 2 designates a sectional view of the built up roll, comprising a plurality of discs, every other one of them being keyed to the shaft, the other discs being idlers having grooves for belts, and the keyed discs being provided with suitable knurled or roughened surfaces.
and the belts being preferably made of flat metal. At a suitable point in relation to the built up rolls are located a pair of guide rolls 12 and .13 mounted on shafts 14 and 15. The numeral 1.6 represents paper as it comes from a supply source preparatory to being received by the pinch rolls 1 and 2. The guide rolls 12 and Y13, and idler discs 8 are adapted to travel at a slower speed than the keyed discs 3, thereby causing the paper 16 to crinkle as it passes the knurled faces 4, and is forced down between the belts 10 and 11. The crinkled nated by the numeral 17.
Heretofore it has been common in the creping of paper to moisten a web by passing it through a bath of water, running it through a pair of press rolls composed of a rubber roll and a chilled steel roll, the moist paper having a tendency to stick to the chilled steel roll and by having the paper that adheres ,to the chilled steel roll run against a so-called doctor blade, and crinkling or creping it in that way.
- This process differs materially from the old'process and is what may be called a dry creping method, nowater or doctor blade being necessary. In the process of making this stretchable paper without moistening,
two rolls are used which are built up of a may receive an endless belt which will go around these rolls and also around the idler discs which are grooved to receive the belt. The built up rolls are driven at a certain speed while the lower rolls on which the belts are guided run at a different speed. The two built up rolls are placed side by side and act as pincher rolls, the knurled surface discs meeting and acting as pincher or driving rolls. These rolls crowd the paper down into the channel which is made up of the belts, and on account of the fact that the belts are driving at a slower speed the paper is crinkled between the walls, and this method results in providing an even crinkled sheet as it emerges from the. lower belt rolls.
I claim 1. A device for the creping of paper, having means for maintaining the paper uniform and under control at all times, consisting of built up crowding rolls on a shaft, having rolls keyed to the shaft, and rolls riding idle thereon between the keyed rolls.
2. A device for the creping of paper, having means for maintaining the paper uniportion is desig-v 'cate'd a pair of rolls grooved so that they form and under control at all times, conl. A device for the ercping ofpaper,l1avsisting of built up crowding rolls having 111g means for muintainlng the paper unlidler elements. form and under control at all times, con- 3. A device for the creping of paper, havsisting of built up crowding rolls. having 5 ing means for maintaining the paper uniidler elements, the idler elements being "form and under control at all times, conadapted to receive an endless belt.
sisting of built up crowding rolls on a shaft In testimony whereof I alfix my signahaving idler elements, the idler elements ture. I being provided with grooves adapted to re- 10 CGlXe an endless belt. PETER J. CHRISTMAN, J n.
