'1 Claims.

The-present invention; relates. to apmethodof and: an apparatus for-producing. artificial sausage skins.

Inzthemanufacture air-artificial sausage skins ita isknown to'impregnate the outeror inner Wallor surface of tubular, fabrics. with. a. suitable fibrous mass consisting, ofsanimal substances such as meat massesv or meattfibres; Forthis purpose, the tubular fabric is jdrawn upwardly through an annular gap and hereby the impregnating mass is; applied within. Oli-=Wi13h01l13 "to, the tubular fabric.

According to the method of the present inven: tionan impregnatingmassisapplied 'to the tubularfabr-ic simultaneously without and within-so that the outeraswell as theinner surface of the-finished tubular fabric-- is coated with an impregnatinglayer. connection with such an impregnation-it is ofparticular'advantage toso carry out thecoating of both 'faces of the-fabric sleevewiththe fibrous material; that the fibres atboth sides or surfaces of the wall of thefabric sleeve cross each other. Hereby a special-reiniorcement of" theimpregnation and therewitha greater strength and durability of the artificial sausageskinis obtained; This is of particular importance ifthe tubular fabrleismadeof arti fi'cial silk which is not as strong asnatural-silk and, moreover, is more sensitive to moisture, Owing to the arrangement of the fibres indireC- tions crossing each other uponthe inner wall and the outer Wall; oftheartificialisausageskin, the lower; strength of i the finishedxtubnlar sausage skinxm-ade of artifiicialsilk iscompensated by the reinforcement of the impregnation and, more! over, the sensitivity; ofrthe artificial silkto moisture, is. rendered in-efiectiveiby; the fact that the tubular fabric iscompl'etely: embedded in the fibrous mass.

The arrangement: of: the fibres-of, the t-Wo-ima pregnatinglayers: in. directions crossin each other: at theinner and": outer surface-of the artificial sausage skin is obtained-in accordance with the; invention by the". fact that the inner and outerwiper members-for the impregnating mass are rotated relatively-t. to each. other, while the tubular iabriceis longitudinally drawn along-these irriemloers.v Hereby: the.- fibres; present in. the im'- n fesnat-ing mass: areaadjustedsin the direction in which the 1 Wiper.- membershmove along: the wall of;

the- .tubular fabric." If; the wiper members are uniformly rotated about the axis ofit-he -mov-ed tubular, iabrimthe, fibres are helically directed, but if the inner wiper members rotate in a direction opposite toe-that: of the outer member, the

fibresare arranged directions crhssing e'aoh other; the angulanpos'it-ion 0f the fibres-'re1a-. tively to each othercor-responding to the speed of; movement of the tubular fabric; as wellas.

- of the wi er-members;- Depending on the speed selected; the fibres may be arranged in a more flat or-steep direction and, moreover; the angular-positionupon the inner orouter 'side-or sur face may-he differently chosen; if thewiper-memhers are rotated withdifferent speedswgalso. v

Any desired length of tubular fabric 7c .ispushed upon aqpipe Z which in turn is pushed over the stand 'pipe. 9 and extends to the bottom of the trough-"a. The end- -(ii-"the; tubular fabric is is Withdrawn from the supportngpipel and pulled upwardly through the bushing e. Within the latter a distance member m having a convex surface is mounted upon the pipe 9. The outer diameter of the distance member m is somewhat smaller than the inner diameter of the bushing 2, so that an annular gap is formed through which the tubular fabric may be drawn.

Within the pipe 9 a long spindle n is rotatably mounted the diameter of which from below the supply pipe it until above the discharge openings z is substantially smaller than the inner diameter of the pipe g, so that the impregnating mass may unimpededly be fed upwardly in the pipe g. Both ends of the spindle n are enlarged to the inner diameter of the pipe 9 so that above and below the mass cannot be discharged. To

this purpose, moreover, special sealing means may be provided at the ends of the pipe g. The

lower end of the spindle is extended through the pipe 9' and carries aworm wheel 0 which by means of a cylindrical projection or rim 3) is journalled in a ball bearing q. The drive of the wormwheel o is effected by the worm r the shaft 8 of which simultaneously drives the worms and worm wheels of the other devices. The drive may be effected by an electromotor.

The upper end of thespindle 12 also extends through the pipe g and is providedwith a square 75 upon which may be mounted two supporting bodies u for the innenwiper members 2;. The latter consist of circular discs the edges of which are rounded off. These discs are rotated by way of the supporting bodies a by means of the spindle it. At the outer side or surface of the tubular fabric 7c another wiper ring w is arranged in a level between the two inner Wiper members 11. The wiper ring'w is fixed to a Worm wheel as rotated by a worm y the shaft 2 of which simultaneously drives the worms of the other devices in the same manner as the lower shaft .9 drives the worms as described above. The Worm wheel it runs on a ball bearing which is supported by way of the bolts or studs 2' from the flange f of the bushing e. I

If the worm wheels 0 and a: are rotated in opposite directions, the inner and outer wiper members 0 and respectively rotate correspondingly and thereby also correspondingly apply the fibres of the impregnating mass to the tubular fabric 1 c, so that the fibres upon the inner and outer side respectively cross each other. Details of the device may, of course, be modified without departing from the spirit of the invention.
