I PROCESS OEMANUFACTUBING VERY EXT NSIBLE' PAPER.

To a7? whom it may concern:

Be it known that l. Anamun'r Grnssnen. a subject of the German Emperor. residing at Niederau, near Diiren. Germany. have invented certain new and useful Improvements in the Process of Manufacturing Very Extensible Paper; and I do hereby declare the following to be a full. clear. and exact descriptioh of the invention. such as will enable others skilled in the aft to which it appertains to make and use the same.

Thesubject-matter of my invention. is an improved process of manufacturing very extensible paper, such as e. pa per or the like.

According to my invention the material is first worked upintovery thingwebs which are united either individually in succession, or in groups and then in these groups in succession. on a long wire-cloth paper-making machine, whereby it is possible to manufacture'heavy paper of very greasy material, the fibers being well felted and a very high degree of extensibility being obtained by working up the material in individi-lal layers.

A particularly suitable form of apparatus for carrying'my improved process into practice comprises several superposed sets of wire-cloth, in which the end guide rolls of r sack or cable the top machine are located in front of and behind the first press-roll of the loweranachine and in this manner admits of an optional number of webs of paper being brought together in long wire-cloth papermaking machines. p

The material employed for manufacturing sack and cable paper is very greasy and therefore can only with difliculty be-treed,

from Water on the long wire-cloth paper .lnaking machinein the case of heavy paper. Consequently the individual fibers of the paper are not felted so readily asin thecase of so-called harshly ('l'bsch) ground material; Now in order to enable thoroughly good telt1ng,; according to my invention the material is Worked up on several sets ot wire-cloths into individual, very thin webs, of paper within which the fibers can felt much more readily on the sets of \virecloths,

and these individual Webs are subsequently united on the lower paper-making machine to form a thick web, and in this manner a specially great degree of strength is given to the product. It is to be emphasized as esscntial that when bringing together such Specification of Letters Patent. Patented Feb, 27, Application tiled March 26, 19th. Serial No. 551,710.

websof paper a very greattdegree of extensibility is obtained both in the transversedirection and in the longitudinal direction of the strip of paper, which is a principal requirement of the product, in order thatthe In a modified, very advantageous mode of carrying my invention into practice an in-- sertion' ot textile material, wire or other sultable material 13 introduced between two or more webs: this insertion comes from a stock 'reel, guided by a guide roll and so placed between the Webs that; it runs in at t i a very acute angle to one of the same and an injurious websfl One form of apparatus suitable ,for'carrying my process into practice is represented by way. of example in the accompanying drawing, five long Wire-cloth paperm'aking pressure against any of the machines being shown superposed. inthree.

Referring to the drawing, the paper Web coming with the Wire-cloth a from the long wire-cloth paper-making machine A is brought, after ithas passed the couchingroll I), bymeans of the end guide roll 0 onto the web of wire-cloth a? ofthe machine B,

this end guide'rollk' being located in 'front of the first press-roll d of the machine B. Simultaneously, the web of paper coming from the machine I over the wire-cloth'2 is supplied, after it has passed the couching-roll I), with the aid of the end'guide roll 3 to the wire-cloth a of themachine B, the end guide roll 3 being located in the direction of working immediately behind the this first press-roll d by the end guide roll 3 so that on the machine B a strip of paper consisting of five webs is brought under the couching roll b It is obvious that the manufacturer can 60' tilled sacks can yield during transit and consequentlyinot tear.

W v p In the form of apparatus represented by wayofeit aniple, insertions E and E of tex? tile material are inserted at two places between the webs the former on'the machine B andthe latter on the machine l3. These insertions coming-from the,\stock .reels R and R are inserted with the aid. of guide rolls TV and W respectively, which-are so 'elose to the web of the paperqn'akin'g ma chine in question that-the insertion.'which is at a veryacute angle tothe iwebt arrives between the webs of paper wlthout'exerclslng an injurious pressure against'the one orthe other.
