  • Shirred casing article loader/unloader
    Patent number: 4914784
    Abstract: Apparatus and method for loading a shirred casing article into a stuffing horn tilted upwardly at a load position with respect to horizontal. The article is moved along a horizontal rail supported above the stuffing horn. The article spills over an end of a rail and onto a chute. The chute is in alignment with the upwardly tilted horn so that a driven member can engage the article and drive it down the chute onto the horn. The driven member is reversible so a spent casing article on the upwardly tilted horn can be unloaded by driving it up the chute to a positions here it spills over the upper end of the chute and discards.

  • Method and apparatus for severing shirred tubular food casing and article
    Patent number: 4885821
    Abstract: The severing of a shirred stick from unshirred casing is accomplished by pressing and annular tear edge directly against the last-shirred end of the stick and tearing unshirred casing away from the stick along this edge. The result is little or no tail of loose casing at the last-shirred end. Characteristically, the resulting torn ends both extend normal to the casing longitudinal axis. In addition, this torn end at the first-shirred end of the stick is clean and continuous whereas the torn end at the last-shirred end of the stick contains one or more tags or loose shreds of casing.

  • Apparatus for monitoring the width of a stuffed food casing
    Patent number: 4837897
    Abstract: Shoes for tracking against the opposite sides of a stuffed casing are carried by two independent parallel motion linkages suspended from two shared shafts. Each linkage is journaled to one shaft and fixed to the other so each link drives only one shaft. Each shaft in turn drives a signal generator so that an electrical signal is generated in response to the movement of the shoes in a plane transverse the longitudinal axis of the stuffed casing as represented by the rotation of the shafts.

  • Method of making a liquid smoke impregnated shirred casing stick
    Patent number: 4818551
    Abstract: A shirred stick composed of unreinforced casing impregnated with liquid smoke. The stick has no twist which eliminates rope and gives the stick a smooth, blemish free outer peripheral surface. The method of making the stick requires placement of the shirred stick on a dowel immediately after shirring, holding it on the dowel for a period of time sufficient for moisture to migrate uniformly throughout the stick and then removing the dowel.

  • Method and apparatus for shirring food casings
    Patent number: 4773127
    Abstract: A shirring method and apparatus for shirring food casing in which the casing is shirred directly onto a sleeve which moves longitudinally through the shirring mechanism from a first position to a second position until a desired length of shirred casing is accumulated on the sleeve. The sleeve is held at its second position and the shirred casing is removed from the sleeve in the direction of shirring and thereafter the sleeve is returned to its first position.

  • Packaged food casing article with attached splice tape
    Patent number: 4771889
    Abstract: A packaged food casing article includes a dispensing carton, a roll of casing rotatably supported within the carton, and a strip of splice tape releasably attached to a carton closure flap. The tape as oriented on the flap extends transverse to the casing dispensing direction and is attachable to an end of the casing when effecting a splice to the casing length being dispensed from the carton. The flap maintains the splice tape in a proper orientation during splicing and provides a work surface against which the casing is pressed for effecting the splice.

  • Size control system for stuffing machine
    Patent number: 4766645
    Abstract: An apparatus for controlling the stuffed casing diameter includes shoes which ride against the stuffed casing to monitor its diameter. These shoes drive a digital encoder which issues pulses representing deviations of the stuffed diameter from a predetermined nominal value. A microcomputer process these pulses and issues an appropriate control signal to a stepping motor for increasing and decreasing drag on the casing as may be needed to correct the stuffed diameter of the casing. The microcomputer can include a delay so that each stuffed product is the reference for establishing the drag characteristics of the next product to be stuffed.

  • Method of making an end closure for a stick of shirred food casing
    Patent number: 4759100
    Abstract: An end closure for a shirred casing stick is formed from casing inturned into the bore of the stick. A vacuum assist is used to prepleat the casing within the bore prior to compaction. The resulting end closure is a generally cylindrical plug composed of accordion-type pleats and having an end portion which has a substantially uniform density about the longitudinal axis of the plug and a second portion which has an asymmetrical density. The second portion has two longitudinally extending sections; one having its pleats formed of a single ply of casing and a diametrically opposite section having its pleats formed of three plies of casing, thereby providing the asymmetric density.
