Abstract
Abstract A tying machine comprising a bundle shaping unit including a pair of side aligning plates and a roller press which enables the bundle to be tied to move in a feeding direction while exercising a compressing force upon the bundle which has had its sides aligned by the side aligning plates. The tying machine also comprises a tying unit including a pair of oppositely disposed tying devices and press means which exercises a compressing force upon the bundle during the tying operation. The bundle to be tied is fed from the bundle shaping unit to the tying unit one by one upon completion of each cycle of the bundle shaping operation of the bundle shaping unit.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
174 words
A tying machine comprising a bundle shaping unit including side aligning means for aligning sides of a bundle to be tied, a tying unit including a pair of tying devices disposed opposite to each other for tying a string around the bundle and press means exercising a compressing force upon the bundle to be tied during the tying operation effected by said tying devices, a feeding device for stopping the bundle during the operation of said bundle shaping unit and feeding the bundle from said bundle shaping unit to said tying unit one by one upon completion of each cycle of the operation of said bundle shaping unit, said feeding device including a conveyer portion associated with said tying unit and defining a predetermined linear path of travel of a bundle between said pair of tying devices, and means for moving said pair of tying devices transversely relative to said predetermined linear path of travel selectively away from or toward each other whereby different tying positions for bundles to be tied can be established.
Claim 2
Dependent Claim
174 words
A tying machine comprising a bundle shaping unit including side aligning means for aligning sides of a bundle to be tied, a tying unit including a pair of tying devices disposed opposite to each other for tying a string around the bundle and press means exercising a compressing force upon the bundle to be tied during the tying operation effected by said tying devices, a feeding device for stopping the bundle during the operation of said bundle shaping unit and feeding the bundle from said bundle shaping unit to said tying unit one by one upon completion of each cycle of the operation of said bundle shaping unit, said feeding device including a conveyer portion associated with said tying unit and defining a predetermined linear path of travel of a bundle between said pair of tying devices, and means for moving said pair of tying devices transversely relative to said predetermined linear path of travel selectively away from or toward each other whereby different tying positions for bundles to be tied can be established.
Claim 3
Dependent Claim
40 words
A tying machine as defined in claim 1 wherein said bundle shaping unit further comprises press means permitting the bundle having had its sides aligned by said side aligning means to move while exercising a compressing force upon the bundle.
Claim 4
Dependent Claim
24 words
A tying machine as defined in claim 2 wherein said press means provided in said bundle shaping unit is a press carrying free rollers.
Claim 5
Dependent Claim
81 words
A tying machine as defined in claim 2 wherein said press means provided in said bundle shaping unit is a press including a roller carrier which is slideable in a longitudinal direction parallel to a feeding direction of the bundle and drive means for driving said roller carrier in the feeding direction of the bundle and rollers carried by said roller carrier are permitted to rotate only when said roller carrier is moved in a direction opposite to the feeding direction.
Claim 6
Dependent Claim
45 words
A typing machine as defined in any of claims 1 to 4 wherein said press means provided in said tying unit includes a press plate provided with a curved portion in at least one end hereof and drive means for vertically moving said press plate.
Claim 7
Dependent Claim
50 words
A tying machine as defined in any of claims 2 to 4 wherein said press means provided in said tying unit includes a free roller conveyer which is controlled in a vertical position thereof in accordance with a vertical position of said press means provided in said bundle shaping unit.
Claim 8
Dependent Claim
59 words
A tying machine as defined in any of claims 1 to 4 wherein said feeding device includes a drive roller conveyer and a stopper actuated in association with the operation of said bundle shaping unit to engage the bundle while the bundle shaping operation is being effected and disengaged from the bundle upon completion of the bundle shaping operation.
Claim 9
Dependent Claim
58 words
A tying machine as defined in any of claims 1 to 4 wherein said tying device includes a wrapping arm which swings between two positions and a string holder provided below said wrapping arm, the string stretched between said wrapping arm and said string holder being wrapped around the bundle to be tied by feeding of the bundle.
Claim 10
Dependent Claim
34 words
A tying machine as defined in claim 1 wherein said moving means includes oppositely threaded bars with each of said bars being threadably connected to an associated one of said pair of tying units.
Claim 11
Dependent Claim
72 words
The tying machine as defined in claim 9 wherein said conveyer portion is a pair of conveyer belts, one conveyer and one tying unit being carried by a frame at one side of said predetermined linear path and another conveyer belt and tying unit being carried by another frame at an opposite side of said predetermined linear path, and said moving means being threadedly connected by opposite thread means to said frames.
Claim 12
Dependent Claim
23 words
The tying machine as defined in claim 10 wherein said moving means includes an oppositely threaded shaft transversely spanning said predetermined linear path.
Claim 13
Dependent Claim
55 words
A tying machine as defined in claim 5 wherein said feeding device includes a drive roller conveyer and a stopper actuated in association with the operation of said bundle shaping unit to engage the bundle while the bundle shaping operation is being effected and disengaged from the bundle upon completion of the bundle shaping operation.
Claim 14
Dependent Claim
55 words
A tying machine as defined in claim 6 wherein said feeding device includes a drive roller conveyer and a stopper actuated in association with the operation of said bundle shaping unit to engage the bundle while the bundle shaping operation is being effected and disengaged from the bundle upon completion of the bundle shaping operation.
Claim 15
Dependent Claim
54 words
A tying machine as defined in claim 5 wherein said tying device includes a wrapping arm which swings between two positions and a string holder provided below said wrapping arm, the string stretched between said wrapping arm and said string holder being wrapped around the bundle to be tied by feeding of the bundle.
Claim 16
Dependent Claim
54 words
A tying machine as defined in claim 6 wherein said tying device includes a wrapping arm which swings between two positions and a string holder provided below said wrapping arm, the string stretched between said wrapping arm and said string holder being wrapped around the bundle to be tied by feeding of the bundle.
Claim 17
Dependent Claim
54 words
A tying machine as defined in claim 7 wherein said tying device includes a wrapping arm which swings between two positions and a string holder provided below said wrapping arm, the string stretched between said wrapping arm and said string holder being wrapped around the bundle to be tied by feeding of the bundle.
