Abstract
A device for continuously imparting a predetermined twist to an elongated tubular shaped flaccid work piece composed of first and second sets of arcuate shaped spaced apart ribs delimiting a space having a funnel shaped portion, a moving device affixed to the first and second set capable of moving the first and second set of ribs in misalignment with one another, and a device for supplying gas under pressure to the space delimited by the first and second sets of ribs.
Claims18
A device for detwisting tubular shaped elongated flaccid material comprising:
- (a) a support;
- (b) first and second sets of arcuate shaped spaced apart ribs disposed on said support, defining a funnel shaped space between said first and second sets of ribs;
- (c) a moving device affixed to said first and second sets of ribs to move the ribs of said first and second sets to a misaligned position with one another;
- and,
- (d) a device for supplying a gas under pressure into said tubular shaped elongated flaccid material while in said space.
2 more elements
A device for detwisting an elongated piece of flaccid material comprising:
- (a) a support;
- (b) a detwister mounted on said support, said detwister including a first and second set of arcuate rib members, each set having first and second rods to which the arcuate rib members of a given set are affixed in a spaced apart manner, the first and second sets being disposed relative to one another so that the first rod of the first set is spaced apart from the first rod of the second set and the second rod of the first set is spaced apart from the second rod of the second set by an amount greater than the distance said first rods are spaced apart from each other, said first and second sets delimiting a space having a funnel shaped portion, said first rods being movable relative to each other to cause said spaced apart ribs of said first set to be misaligned with the spaced apart ribs of the second set, and one or more of said ribs having apertures therein attached to a source of gas under pressure for providing a supply of gas into said space at a first level of supply.
