Method for forming tubes in nets
View Patent ↗A net derucking rectifier system is described. The system has a stuffer, a product horn having an upstream end and a downstream end, the upstream end mounted to the stuffer, a netting tube having an upstream end and a downstream end, the netting tube removably mounted coaxially over the product horn and having a tubular netting shirred thereon, a bracket mounted coaxially to the netting tube and having a plurality of fingers pointing radially inward to grip the netting, the bracket movable between a first position near the upstream end and a second position near the downstream end, the fingers biased to grip the netting when the bracket is moved from the first position to the second position and not to grip the netting when the bracket is moved from the second position to the first position, and a clipper located adjacent the distal end of the netting tube. In another embodiment, a method of derucking a predetermined length of netting rucked on a tube, comprises gripping the netting in a first position on the tube, moving the gripped netting from the first position to a second position a predetermined distance axially along the tube, releasing the netting at the second position, and regripping the netting at the first position.
1. A method for encasing material in casing and netting, comprising:
providing a stuffer;
providing a product horn having an upstream end and a downstream end, said upstream end mounted to said stuffer;
shirring a tubular netting onto a netting tube, said netting tube having an upstream end and a downstream end;
mounting said netting tube coaxially over said product horn;
providing a bracket comprising a pair of jaws, said jaws being separable a distance at least as great as a diameter of said netting tube, said jaws closable to form an annulus, said bracket comprising a plurality of fingers pointing inward;
mounting said bracket coaxially to said netting tube;
moving said bracket between a first position near said upstream end of said netting tube and a second position near said downstream end of said netting tube;
biasing said fingers to grip said netting when said bracket is moved from said first position to said second position and not to grip said netting when said bracket is moved from said second position to said first position; and
clipping said netting at said distal end of said netting tube.
2. The method of claim 1 , wherein said biasing said fingers step comprises spring-loading said fingers.
3. A method for rectifying netting, comprising:
shirring a tubular netting onto a netting tube, said netting tube having an upstream end and a downstream end;
mounting said netting tube coaxially over a product horn, said product horn having an upstream end and a downstream end;
providing a bracket comprising a pair of jaws, said jaws being separable a distance at least as great as a diameter of said netting tube, said jaws closable to form an annulus, said bracket comprising a plurality of fingers pointing inward;
mounting said bracket coaxially to said netting tube;
moving said bracket between a first position near said upstream end of said netting tube and a second position near said downstream end of said netting tube; and
biasing said fingers to grip said netting when said bracket is moved from said first position to said second position and not to grip said netting when said bracket is moved from said second position to said first position.
4. The method of claim 3 , wherein said biasing said fingers step comprises spring-loading said fingers.
