Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
105 words
A device for depositing weft thread supply for weaving machines having feeding and withdrawing mechanisms for the thread, said device being arranged between the feeding and withdrawing means and comprising an inserter, a magazine in the shape of a body of revolution, a plurality of uniformly arranged ribs projecting towards the axis of said body of revolution and being mounted thereon, said ribs defining gaps therebetween, said inserter being adapted to deposit said thread in said magazine so as to extend across opposite edges of said ribs and into said gaps between adjacent ribs and means for relatively rotatably driving the said magazine and inserter.
Claim 2
Independent Claim
105 words
A device for depositing weft thread supply for weaving machines having feeding and withdrawing mechanisms for the thread, said device being arranged between the feeding and withdrawing means and comprising an inserter, a magazine in the shape of a body of revolution, a plurality of uniformly arranged ribs projecting towards the axis of said body of revolution and being mounted thereon, said ribs defining gaps therebetween, said inserter being adapted to deposit said thread in said magazine so as to extend across opposite edges of said ribs and into said gaps between adjacent ribs and means for relatively rotatably driving the said magazine and inserter.
Claim 3
Dependent Claim
28 words
A device as claimed in claim 1, wherein the ribs of the magazine have a flat face and are radially arranged relative to the axis of the magazine.
Claim 4
Dependent Claim
42 words
A device as claimed in claim 2, wherein the ribs of the magazine are formed by blades of substantially triangular shape, said blades being arranged with their bases about the circumference of the magazine, the vertices of successive blades being mutually staggered.
Claim 5
Dependent Claim
29 words
A device as claimed in claim 1, wherein the inserter is of tubular shape and is provided with a supply of fluid pressure medium to accelerate the inserted thread.
