Abstract
Abstract A rotatable holder has a plurality of parallel carriers onto which sausage casings are gathered. The holder rotates to dip the casings sequentially in a treating liquid after which the carriers and casings emerge. When a carrier is aligned with a filling tube of a sausage-filling machine, the casing is transferred still in gathered condition from said carrier to said tube. Means are provided to hold the casing in place and to facilitate start up of filling of a new casing.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
77 words
A process for applying an artificial casing to a filling tube of a sausage-filling machine, comprising placing said casing on a carrier in gathered bellows-like form, retaining said casing in such gathered form on said carrier, immersing said carrier and casing in an aqueous fluid thereby to treat said casing, withdrawing said carrier and its casing from the fluid, and transferring said treated casing from said carrier to said tube while maintaining the casing in gathered condition.
Claim 2
Dependent Claim
77 words
A process for applying an artificial casing to a filling tube of a sausage-filling machine, comprising placing said casing on a carrier in gathered bellows-like form, retaining said casing in such gathered form on said carrier, immersing said carrier and casing in an aqueous fluid thereby to treat said casing, withdrawing said carrier and its casing from the fluid, and transferring said treated casing from said carrier to said tube while maintaining the casing in gathered condition.
Claim 3
Dependent Claim
40 words
A process according to claim 1, wherein a plurality of carriers are included and they are sequentially provided with casings, the casing being transferred from one carrier to the filling tube while another carrier and its casing are undergoing treatment.
Claim 4
Dependent Claim
28 words
A process according to claim 1, including the further step of securing the gathered casing on the filling tube after the transfer until filling of the casing commences.
Claim 5
Dependent Claim
39 words
A process according to claim 1, wherein transfer of a treated casing from its carrier to a filling tube is effected in synchronism with completion of a sausage-filling operation on a casing which has previously gone through the process.
Claim 6
Independent Claim
102 words
An apparatus comprising in combination a sausage-filling machine having at least one filling tube and a casing treating machine, the treating machine comprising a tank for holding a treating fluid, means for supplying treating fluid to said tank and for removing treating fluid therefrom, at least one carrier onto which a casing can be gathered in bellows-like form outside said treating fluid, means for immersing the carrier with the casing into treating fluid in said tank and then for removing the carrier and casing from the treating fluid, and means for transferring the treated casing from said carrier to said filling tube.
Claim 7
Independent Claim
102 words
An apparatus comprising in combination a sausage-filling machine having at least one filling tube and a casing treating machine, the treating machine comprising a tank for holding a treating fluid, means for supplying treating fluid to said tank and for removing treating fluid therefrom, at least one carrier onto which a casing can be gathered in bellows-like form outside said treating fluid, means for immersing the carrier with the casing into treating fluid in said tank and then for removing the carrier and casing from the treating fluid, and means for transferring the treated casing from said carrier to said filling tube.
Claim 8
Dependent Claim
54 words
An apparatus according to claim 5, wherein a plurality of carriers are provided, the immersing and removing means including a holder onto which one end of each carrier is mounted, and means for rotating said holder so as successively to immerse and then remove the carriers and casings from treating fluid in the tank.
Claim 9
Dependent Claim
50 words
An apparatus according to claim 6, wherein the holder is star shaped and rotatable about an axis parallel to the axes of the carriers, the transfer means including a pusher displaceable in longitudinal direction of the carriers, said pusher operating when a carrier is in alignment with a filling tube.
Claim 10
Dependent Claim
27 words
An apparatus according to claim 5, including first resilient means operatively connected with said carrier for holding a gathered casing onto said carrier during immersion and removal.
Claim 11
Dependent Claim
44 words
An apparatus according to claim 6, including a further tube carried on said holder and of a diameter insufficient to contact directly a gathered casing on a carrier on said holder, said further tube being coaxially with the axis of rotation of said holder.
Claim 12
Dependent Claim
34 words
An apparatus according to claim 9, including second resilient means on said further tube, said second resilient means additionally serving to retain a casing in gathered condition on a carrier during immersion and removal.
Claim 13
Dependent Claim
24 words
An apparatus according to claim 5, including third resilient means for holding the gathered casing on the filling tube after transfer from a carrier.
Claim 14
Dependent Claim
60 words
An apparatus according to claim 5, including a pivotally mounted casing snubber in operative position snubbing the downstream end of a casing on the filling tube, and means for pivoting said snubber to inoperative position where it is out of the path of operation of the transfer means in transferring a gathered casing from a carrier to said filling tube.
Claim 15
Dependent Claim
35 words
An apparatus according to claim 12, said sausage-filling machine including a rotatable turret carrying a plurality of filling tubes, each filling tube being provided with a respective snubber rotating therewith upon rotation of said turret.
Claim 16
Dependent Claim
30 words
An apparatus according to claim 6, wherein said means for rotating said holder operates intermittently so that each carrier remains statically in immersed position for a predetermined length of time.
Claim 17
Dependent Claim
69 words
An apparatus according to claim 5, said treating machine including a pump for circulating treating fluid in said tank, a filter for removing solids from the circulating treating fluid undergoing pumping, means for supplying treating fluid to said tank, means for discontinuing supply of treating fluid when it reaches a predetermined height in said tank, and means for heating the treating fluid in said tank to a predetermined temperature.
Claim 18
Dependent Claim
45 words
An apparatus according to claim 5, including means for gripping and pulling forwardly the downstream end of the gathered casing on the filling tube after transfer of the casing from the carrier to the filling tube immediately prior to the initiation of a filling operation.
Claim 19
Dependent Claim
61 words
An apparatus according to claim 16, including a parallelogram swinging mechansim actuating said gripping and pulling means, said mechanism being disposed so that upon swinging said parallelogram from a first position where said gripping means is operative to a second position where inoperative the gripping means is outside the normal line of advance of filled casings coming off the filling tube.
Claim 20
Dependent Claim
43 words
An apparatus according to claim 17, including piston and cylinder means operatively connected with said parallelogram swinging mechanism to move the latter between said first and second positions, said piston and cylinder means being operatively connected to and controlled by the filling machine.
