Abstract
Abstract A device for the manufacture of a non-woven, reticulate textile strip comprising two longitudinally movable, at least partly parallel conveyors, bearing a plurality of hooks having free ends bent over forwardly and downwardly in the direction of movement of the conveyors and not exhibiting outwardly projecting parts with respect to the fastening point on the conveyors and at least one reciprocating thread feeder adapted to move between the outer sides of the two conveyors, the reciprocating thread feeder preferably being guided along an arc and driven by a driving means adapted for driving said thread feeder with a uniform acceleration and retardation along said arc in conformity with the natural oscillation of said thread feeder.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
90 words
A device for the manufacture of a non-woven, reticulate textile strip comprising two longitudinally movable, at least partly parallel conveyors, on which a plurality of thread retaining members are fastened, and at least one changing thread feeder adapted to move between the outer sides of the two conveyors, characterized in that the retaining members are formed by hooks having free ends bent over forwardly and downwardly in the direction of movement of the conveyors, said hooks not exhibiting outwardly projecting parts with respect to the fastening point on the conveyors.
Claim 2
Independent Claim
90 words
A device for the manufacture of a non-woven, reticulate textile strip comprising two longitudinally movable, at least partly parallel conveyors, on which a plurality of thread retaining members are fastened, and at least one changing thread feeder adapted to move between the outer sides of the two conveyors, characterized in that the retaining members are formed by hooks having free ends bent over forwardly and downwardly in the direction of movement of the conveyors, said hooks not exhibiting outwardly projecting parts with respect to the fastening point on the conveyors.
Claim 3
Independent Claim
90 words
A device for the manufacture of a non-woven, reticulate textile strip comprising two longitudinally movable, at least partly parallel conveyors, on which a plurality of thread retaining members are fastened, and at least one changing thread feeder adapted to move between the outer sides of the two conveyors, characterized in that the retaining members are formed by hooks having free ends bent over forwardly and downwardly in the direction of movement of the conveyors, said hooks not exhibiting outwardly projecting parts with respect to the fastening point on the conveyors.
Claim 4
Independent Claim
90 words
A device for the manufacture of a non-woven, reticulate textile strip comprising two longitudinally movable, at least partly parallel conveyors, on which a plurality of thread retaining members are fastened, and at least one changing thread feeder adapted to move between the outer sides of the two conveyors, characterized in that the retaining members are formed by hooks having free ends bent over forwardly and downwardly in the direction of movement of the conveyors, said hooks not exhibiting outwardly projecting parts with respect to the fastening point on the conveyors.
Claim 5
Dependent Claim
19 words
A device as claimed in claim 1, characterized in that the hooks are inclined inwardly by the bent-over ends.
Claim 6
Dependent Claim
51 words
A device as claimed in claim 1, characterized in that the reciprocable thread feeder is guided along an arc and is driven by a driving means adapted for driving said thread feeder with a uniform acceleration and retardation along said arc in conformity with the natural oscillation of said thread feeder.
Claim 7
Dependent Claim
86 words
A device as claimed in claim 1 characterized in that the hooks on one conveyor are each provided with a slipping clamp and those on the other conveyor are provided with a non-slipping clamp for the threads, a cutter being arranged inwardly at the side of the conveyor having the non-slipping clamps for one layer of the threads arranged in two layers between the hooks, whilst beyond said cutter one of the conveyors partly covers a path diverging from the straight path of the other conveyor.
