To all whom z't may concer/lt.'

' Be it known that I, BARTLETT ARKELL, a citizen of the United States, residing in the borough of Manhattan, city, county, and State of New York, have invented certain new and useful Improvements in Machines for Making Stretchable Crinkled Paper, of which the following is a full, clear', and exact description.

This invention relates to a machine for making stretchable' crinkled paper of the type that is used for packing and wrapping purposes.

In the manufacture of crinkled paper it is desirable that the paper be moistened before it is placed on the receiving roll and acted upon by the doctor to form the crinkles in the paper. After the paper has received these crinkles, it must again be dried and in such a manner that the crinkles are not destroyed during the drying. The drying process requires a Iconsiderable amount of heat and renders the rooms more or less uncomfortable.

It is an object of this invention to condition the paper while inl theweb for being placed upon the receiving roll so that it may be crinkled by the doctor with a minimum amount of moisture content. By so reducing the moisture content less heating will be required to subsequently dry the crinkled paper.l

Another object of my invention is to subject the paper while in the web to successive wetting and squeezing operations, so that the moisture will be compelled to permeate all parts of the web.

Other objects of the invention will appear as the description proceeds.

In the drawings, wherein I have shown three of the many possible embodiments of my invention,

Figure 1 is an elevation of the machine showing the essential parts of the completed machine;

Fig. 2 is a section taken on plane 22 of Fig. l;

Fig. 3 is an elevational view of a machine modified from what is shown in Fig. 1 and showing but one of the wetting and squeez-l ing devices; and

Fig. 4 is a view similar to F ig. 3 showing a further modified form.

According to the form of the invention, as shown in Figs, 1 and 2, a main frame 5 kbe adjusted.

carries at one end a suitable supporting bracket 6 for the roll 7 of finished paper from which it is fed while in the web as at 8 to the various parts of the machine.

Also mounted on this frame is a tank or receptacle 9 adapted to contain a bath 10. In this bath a plurality of immersing rolls. 11 .are carried, these rolls being submerged in the bath 10. On the top ofthe frame and over the tank 9, a plurality of squeezing devices are located. These squeezing devices 12 comprise a fixed rubber-faced roll 13 and an adjustable rubber-faced roll 14 mounted in suitable boxes 15 and provided with compressible springs 16 and hand wheels 17 whereby the pressure between the rolls may The first roll at the left, as shown in Fig. 1, is preferably placed substantially so that its axis is located directly above the axes of the immersing rolls 11 and halfway between them. In the form shown, three sets of immersing rolls 11 and three sets of squeezing devices 12 are shown. I do not intend to limit myself to three such devices, for I mav use more or less as conditions require, and I may not use all of the devices on a machine at all times. j

lAt the opposite endof the frame 5. a power shaft 18 is mounted, which carries a suitable driving pulley 19 at one end, and another driving pulley 20 on the opposite end. A belt passes over the pulley 20 and about a suitable pulley arranged at one end of one of the squeezlng rolls. As shown, it connects with a pulley 21 carried on the back side of the right hand squeezing `device. Another pulley 22 is carried on the front side of the first squeezing device. The other two squeezing devices carry the same sized pulleys and are driven by the

belts

23 and 24 as shown. i

Also driven from the shaft 18 is a receiving roll 25 and: associated with this re ceiving roll is the doctor blade 26 which crinkles the paper as it is driven against it. Near the receiving roll 25 an adjustable pressure roll 27 is also carried by the main frame.

The web 8 of paper, as it oomesfrom the roll 7, is directed over a. roller 28 and under the left immersing rollll. It then goes upwardly and about the lower roll 13 of the left side of squeezing devices, where any' excess moisture will be expelled and where the moisture will be forced through the squeezing device the paper is fed under the v next immersing roll 1l. rlFhe paper is passed from this immersing roll through the next squeezing and immersing rolls which act in succession on it. t

The main driving belt 29, acting on pulley 19, draws the paper through the machine and as it passes it about the rece1ving roll and against the doctor blade 26, the paper is taken off the receiving roll in a crinkled condition.

According to the modification of the in.

vention shown in Fig. 3, the web 8 of paper is passed between two pipes which carry water under pressure, the pipes having suitable holes 31 therein so that the water is forced out in the form of a light spray against the paper from both sides. The wetted sheet is then passed through squeezing devices 12 similar to the squeezing` devices l2 before described. rlhe drawing shows but one set of wetting and squeezing devices, but it is understood that a plurality of each of these is contemplated, and that the paper will pass through them in succession.

According to the modification shown in Fig. 4, the web 8 is wetted by being passed between rollers 32 and 33. The roll 33 has a felt covering'i, and is supplied from the interior 35 through perforations 35 with water to wet the felt. rllhe wetted felt will then dampen the paper as it is passed through. Similar squeezing devices 12 are used as before, and a plurality of wetting and squeezing devices is contemplated.

For some qualities and weights of paper more immersing and squeezing operations will be necessary than for other types of paper, and in the case of paper requiring fewer wettings and squeezings than the machine is capable of applying, the web may be directed so that it will not pass about. all the immersion rolls 11, that is, it might go directly from roll 28 to the left squeezingl device l2, or fromV one squeezing device direct to the other.

The water or other liquid with which the paper is wet should be hot and preferably near the boiling point as high temperature of the wetting liquid promotes penne-ation of the paper. lf desired, the pipes 30 in lFig. 3 may supply steamto wet the paper instead of water or other liquid.

iVfhile lf have shown'the invention and its modifications in what l believe to'be the best and most efficient form, it will be understood that various changes may be made without departing from tlie scope of the invention.
