Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
258 words
A binding machine for binding objects with wire, comprising a device (6) for feeding and stretching the wire; a track (8) for guiding the wire around an object to be bound; a locking unit comprising a stop member (29) for the free wire end as well as a movable (30) and a stationary (31) tongs part for locking the free wire end; a twisting unit comprising a rotary twisting roller (36) in the form of a toothed wheel provided with a radial slit (37) for twisting the wire parts; a cutting unit comprising a movable (48) and a stationary (47) cutting member for cutting off the wire; a openable guide bar (10) for guiding the wire between the units; lever means (32) for operating the movable tongs part (30); a lever member (50) for operating the movable cutting member (48); lever means (27a, 27b) for operating the openable guide bar (10); and transmitting wheels (39) (40) for transmitting drive force to the twisting roller (36); said locking unit, twisting unit, cutting unit, openable guide bar, lever means, lever member and transmitting wheels all being assembled in one binding unit (9), and a drive unit (25) attached to the binding unit (9) for driving the parts assembled in said bindiNg unit (9), said binding machine being further characterized in that said lever means and said lever member and, respectively, the transmitting wheels are adapted to be driven only by frictional contact with drive means (33, 34, 51, 52), and, respectively, a drive wheel (38) in said drive unit (25).
Claim 2
Dependent Claim
258 words
A binding machine for binding objects with wire, comprising a device (6) for feeding and stretching the wire; a track (8) for guiding the wire around an object to be bound; a locking unit comprising a stop member (29) for the free wire end as well as a movable (30) and a stationary (31) tongs part for locking the free wire end; a twisting unit comprising a rotary twisting roller (36) in the form of a toothed wheel provided with a radial slit (37) for twisting the wire parts; a cutting unit comprising a movable (48) and a stationary (47) cutting member for cutting off the wire; a openable guide bar (10) for guiding the wire between the units; lever means (32) for operating the movable tongs part (30); a lever member (50) for operating the movable cutting member (48); lever means (27a, 27b) for operating the openable guide bar (10); and transmitting wheels (39) (40) for transmitting drive force to the twisting roller (36); said locking unit, twisting unit, cutting unit, openable guide bar, lever means, lever member and transmitting wheels all being assembled in one binding unit (9), and a drive unit (25) attached to the binding unit (9) for driving the parts assembled in said bindiNg unit (9), said binding machine being further characterized in that said lever means and said lever member and, respectively, the transmitting wheels are adapted to be driven only by frictional contact with drive means (33, 34, 51, 52), and, respectively, a drive wheel (38) in said drive unit (25).
Claim 3
Dependent Claim
35 words
A binding machine according to claim 1, characterized in that the stop member (29) is a one-wire passageway, and that the free wire end is stopped between said member and the wire in said passageway.
Claim 4
Dependent Claim
51 words
A binding machine according to claim 1 characterized in that the same comprises an ejector member (43) for ejecting the completely twisted tie from the binding unit (9) is positioned on both sides of the twisting roller (36), and that the ejector member (43) is actuated by piston means (45, 46).
Claim 5
Dependent Claim
51 words
A binding machine according to claim 1, characterized in that the aforesaid radial slit (37) in the toothed wheel constituting the twisting roller (36) replaces a tooth in the wheel, and that the driving is effected via two transmitting wheels (39, 40) offset in the circumferential direction of the twisting roller.
Claim 6
Dependent Claim
62 words
A binding machine according to claim 1, characterized in that during the stretching and twisting operation the wire parts are retained in the binding unit (9) by the locking unit and cutting unit, and that the movable cutting member (48) is provided with a pin (56), which prevents the wire from being drawn out of the cutting unit during the stretching operation.
Claim 7
Dependent Claim
30 words
A binding machine according to claim 1, characterized in that the distance between the binding unit (9) and the adjacent side of the object to be bound (1) is adjustable.
Claim 8
Dependent Claim
67 words
A binding machine according to claim 1, characterized in that piston means (33, 34) are provided to actuate, via the lever (32) in the binding unit (9) the movable tongs part (30) and that piston means (51, 52) are provided to actuate via lever (50), the movable cutting member (48) and that piston means are provided to actuate, via lever (27a, 27b), the openable guide bar (10).
Claim 9
Dependent Claim
20 words
A binding machine according to claim 7 characterized in that all levers are rotatable about shafts having a common centre.
