Abstract
Abstract A record and an open ended bag are conveyed along different paths at right angles to each other, but in the same plane, insertion of the record into the bag taking place at the intersection of the paths. As the bag is being conveyed it passes between a pair of rotatable eccentric suction rollers which grip the front and back faces of the bag respectively and cause the bag to be opened as the surfaces of the rollers move apart, due to the rotation of the rollers.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
150 words
A device for inserting a record or like article in a bag, comprising an insertion station, means for opening said bag and means for feeding the record or like article into the open bag at said insertion station, in which said opening means comprises a pair of eccentric rollers, means for driving said rollers in phase, means for feeding a bag between said rollers with its open end adjacent to one end of said rollers, the bag feeding means and the roller driving means being so synchronized that as the bag enters between the rollers the surfaces of the latter are at their position of closest approach, while as the bag passes on, towards said station between the rollers their surfaces separate, and suction means associated with said rollers so that front and back faces of the bag are held against the surfaces of the rollers as the surfaces separate.
Claim 2
Independent Claim
150 words
A device for inserting a record or like article in a bag, comprising an insertion station, means for opening said bag and means for feeding the record or like article into the open bag at said insertion station, in which said opening means comprises a pair of eccentric rollers, means for driving said rollers in phase, means for feeding a bag between said rollers with its open end adjacent to one end of said rollers, the bag feeding means and the roller driving means being so synchronized that as the bag enters between the rollers the surfaces of the latter are at their position of closest approach, while as the bag passes on, towards said station between the rollers their surfaces separate, and suction means associated with said rollers so that front and back faces of the bag are held against the surfaces of the rollers as the surfaces separate.
Claim 3
Dependent Claim
41 words
A device as claimed in claim 1 in which the bag feeding means and the roller driving means are so synchronized that the surfaces of said eccentric rollers are at their greatest distance apart when the bag is at said station.
Claim 4
Dependent Claim
99 words
A device as claimed in claim 2 in which said bag feeding means comprises a driven roller and a further roller resiliently urged towards said driven roller, and a perforated conveyor having suction applied thereto, said driven and said further roller being so positioned as to grip said bag therebetween adjacent to its open end, said perforated conveyor being adapted and positioned so as to suctionally support the closed end of said bag opposite said open end, said driven roller, further roller, and perforated conveyor being adapted to feed the said bag along a first path to said station.
Claim 5
Dependent Claim
70 words
A device as claimed in claim 3 in which said record or like article feeding means comprises a chain conveyor provided with pusher means which engage said record or like article to feed it along a second path in the same plane as said first path, but at an angle thereto so as to insert said record or like article in said bag while said bag is at said station.
Claim 6
Dependent Claim
20 words
A device as claimed in claim 4 in which said second path is at right angles to said first path.
Claim 7
Dependent Claim
66 words
A device as claimed in claim 4 in which said second path is defined by guide means comprising a pair of parallel bars, the mutually facing sides of which are each formed with a V-shaped groove extending along its length, said bars being so positioned as to permit each record or like article to be supported in said grooves at diametrically opposite points on its periphery.
Claim 8
Dependent Claim
64 words
A device as claimed in claim 6 in which said pusher means comprises two lugs, each having a face formed with a V-shaped groove for engagement with each record or like article, said grooves coacting with the grooves in said parallel bars to prevent said record or like article from tipping while it is being fed along said second path and into said bag.
Claim 9
Dependent Claim
85 words
A device as claimed in claim 4 in which said pusher means is arranged to continue to feed said record or like article along said second path after said record has been completely inserted in said bag so as to move the bag away from the said eccentric rollers and bring the closed end of said bag into contact with A resilient pad, and means being provided to disengage said pusher means from said record or like article after said bag contacts said resilient pad.
