Abstract
Abstract Machine for tying up a coil of metal wire and the like by means of a tie. The tie is folded about a cross-section of the coil and the end portions of the tie are bent into a hair-pin shape and the desired tension is imparted to the tie by acting on the hairpin shaped portions. Thereafter, the hair-pin shaped portions are twisted by a twisting device, the twisting progressing in a direction from the coil cross-section to the free ends of the tie. A plurality of ties may be arranged around the coil, put under tension and twisted by a plurality of tying units. The twisted portions of the tie are disposed inside the coil.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
294 words
A machine for tying up a coil of filament, such as wire, comprising a first plate and a second plate which are substantially parallel to each other, means for supporting the coil substantially in a plane parallel to the plates, the coil having an axis about which axis the filament extends in the coil, said axis being substantially perpendicular to the plates, means for moving the plates towards and away from each other, at least one supply device for supplying lengths of tie disposed in the vicinity of the first plate, there being associated with the supply device: a deflector disposed on the second plate in facing relation to the supply device for bending a first portion of the tie at about 90* to a remaining portion of the tie about a cross section of the coil to be tied up, a first jaw pivotally mounted on the first plate for taking hold of a second portion of the tie and folding it around the cross section of the coil in the direction of the first portion of the tie, a second jaw mounted on the second plate and movable in translation in a direction substantially perpendicular to the second plate for engaging the first portion of the tie and folding a portion of the first portion of the tie inside the coil about the cross section of the coil, a twisting head mounted on one of the plates to be rotatable about an axis of rotation transverse to said coil axis and located between the plates for twisting end portions of the tie which have been brought in proximity to each other whereby the twisted portions are located inside the coil, and meaNs for rotating the twisting head about said axis of rotation.

A machine for tying up a coil of filament, such as wire, comprising a first plate and a second plate which are substantially parallel to each other, means for supporting the coil substantially in a plane parallel to the plates, the coil having an axis about which axis the filament extends in the coil, said axis being substantially perpendicular to the plates, means for moving the plates towards and away from each other, at least one supply device for supplying lengths of tie disposed in the vicinity of the first plate, there being associated with the supply device: a deflector disposed on the second plate in facing relation to the supply device for bending a first portion of the tie at about 90* to a remaining portion of the tie about a cross section of the coil to be tied up, a first jaw pivotally mounted on the first plate for taking hold of a second portion of the tie and folding it around the cross section of the coil in the direction of the first portion of the tie, a second jaw mounted on the second plate and movable in translation in a direction substantially perpendicular to the second plate for engaging the first portion of the tie and folding a portion of the first portion of the tie inside the coil about the cross section of the coil, a twisting head mounted on one of the plates to be rotatable about an axis of rotation transverse to said coil axis and located between the plates for twisting end portions of the tie which have been brought in proximity to each other whereby the twisted portions are located inside the coil, and meaNs for rotating the twisting head about said axis of rotation.
Claim 3
Dependent Claim
42 words
A machine as claimed in claim 1, wherein the end portions of the two jaws constitute a male seizing portion and a female seizing portion whereby the end portions of the tie are trapped between, without being clamped by, the seizing portions.
Claim 4
Dependent Claim
36 words
A machine as claimed in claim 1, comprising deflectors disposed on each side of the twisting head for guiding and bending end portions of the tie before said end portions are seized by the twisting head.
Claim 5
Dependent Claim
72 words
A machine as claimed in claim 1, comprising a plurality of first jaws, a plurality of second jaws, and a plurality of associated twisting heads arranged in angularly spaced relation about said coil axis for the purpose of simultaneously effecting a plurality of tying operations on the coil in circumferentially spaced regions of the coil, said means for rotating being a single drive means drivingly connected to the plurality of twisting heads.
Claim 6
Dependent Claim
29 words
A machine as claimed in claim 1, further comprising a first carriage carrying the plates and means for moving the first carriage in a direction parallel to said plates.
Claim 7
Dependent Claim
35 words
A machine as claimed in claim 5, further comprising a second carriage movable in a direction perpendicular to the direction of movement of the first carriage, said supply device being mounted on the second carriage.
Claim 8
Dependent Claim
29 words
A machine as claimed in claim 1, comprising means for stopping the movement of each of the plates while moving the other of the plates toward said each plate.
Claim 9
Dependent Claim
89 words
A machine as claimed in claim 1, wherein the supply device comprises a magazine adapted to contain lengths of superimposed ties, a support member at the base of the magazine for a bottom length of tie, a vibrator mounted on the magazine and adapted and arranged to destroy any equilibrium of the lengths of ties, a ram actuated by a fluid motor for urging said bottom length of tie out of the magazine, and driving rollers for urging said bottom length of tie in the direction of said deflector.
