Abstract
Abstract A device for positioning overlapping ends of a looped band in a working area of an automatic packaging machine. The device includes a first slider on one side of the working area and a second slider on the other side of the working area. A driving mechanism coupled to the slider moves them toward each other up to a predetermined distance corresponding to the width of the band in the working area of the packaging machine.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
105 words
A device for positioning overlapping ends of a band in a working area of a machine comprising: a first slider moveable on one side of said working area; a second slider moveable on the other side of said working area; a driving means coupled to said sliders for moving said sliders towards each other up to a predetermined distance corresponding to the width of said band; a band-end stop lever positionable in said working area; and a separating slider positionable in said working area, said band-end stop lever and said separating slider being coupled to said driving means for movement transversely of said working area.
Claim 2
Independent Claim
105 words
A device for positioning overlapping ends of a band in a working area of a machine comprising: a first slider moveable on one side of said working area; a second slider moveable on the other side of said working area; a driving means coupled to said sliders for moving said sliders towards each other up to a predetermined distance corresponding to the width of said band; a band-end stop lever positionable in said working area; and a separating slider positionable in said working area, said band-end stop lever and said separating slider being coupled to said driving means for movement transversely of said working area.
Claim 3
Dependent Claim
80 words
The device as claimed in claim 1, wherein each of said sliders includes a pair of vertically oriented parallel centering plates, one of said pairs being positioned on one side of said working area, and the other pair being spaced apart from said one pair and positioned on the other side of said working area, the edges of apposing pairs of centering plates facing each other for aligning said ends of a band when said sliders move towards each other.
Claim 4
Dependent Claim
22 words
The device as claimed in claim 1, wherein said adjusting means includes a rotatable stop lever cooperating with a stationary adjustable stop.
Claim 5
Dependent Claim
27 words
The device as claimed in claim 1, wherein said driving means includes adjusting means, whereby said predetermined area can be adjusted to accommodate bands of different widths.
Claim 6
Independent Claim
102 words
A device for positioning overlapping ends of a band in a working area of a machine comprising: a first slider moveable on one side of said working area; a second slider moveable on the other side of said working area; and a driving means coupled to said sliders for moving said sliders towards each other up to a predetermined distance corresponding to the width of said band; and wherein said first slider is moveable a further distance from said working area than said second slider, whereby said band can be removed from said working area in a direction toward said first slider.
Claim 7
Independent Claim
102 words
A device for positioning overlapping ends of a band in a working area of a machine comprising: a first slider moveable on one side of said working area; a second slider moveable on the other side of said working area; and a driving means coupled to said sliders for moving said sliders towards each other up to a predetermined distance corresponding to the width of said band; and wherein said first slider is moveable a further distance from said working area than said second slider, whereby said band can be removed from said working area in a direction toward said first slider.
Claim 8
Dependent Claim
64 words
The device as claimed in claim 5, wherein said driving means includes a follower means coupling said first slider to said second slider, said follower means including a lost motion means, whereby said first slider is moved said further distance by said driving means until both said sliders are equidistant from said work area whereupon both said sliders are moved toward said work area.
