Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
264 words
An apparatus for bagging articles handled at a check-out counter, comprising a housing, a bagging compartment in said housing, a top wall of said housing, means defining an opening in said top wall giving access from above to said bagging compartment, a carriage assembly in said bagging compartment vertically movable towards and away from the opening in said top wall, supply means mounted in said housing for supplying rolled flattened tubular foil of heat sealable material to said carriage assembly, bag supporting means on said carriage assembly, means forming a slot in said bag supporting means, feeding and guiding means mounted on said carriage assembly below said bag supporting means for feeding an end portion of the flattened tubular foil upwards through the slot in said bag supporting means towards the opening in said top wall, gripping means mounted in said housing between the opening in said top wall and said carriage assembly for opening and gripping the end of the tubular foil fed upwards through the slot in said bag supporting means, said means forming the slot in said bag supporting means maintaining the tubular foil in substantially flattened condition in the region of said bag supporting means, and bag bottom forming means mounted on said carriage assembly below said bag supporting means for forming a sealed bag bottom by heat sealing the tubular foil in flattened condition along a line transverse to the longitudinal direction of the tubular foil and for severing the bag bottom formed from the length of flattened tubular foil extending from the bag bottom towards said supply means.

Claim 3
Dependent Claim
29 words
An apparatus according to claim 1 further Comprising motor driven means mounted in said housing and connected to said carriage assembly for reciprocating said carriage assembly in vertical direction.
Claim 4
Dependent Claim
113 words
An apparatus according to claim 1 in which said feeding and guiding means comprise a motor driven roller pair mounted on said carriage assembly for engaging and feeding the flattened tubular foil upwards, two shafts mounted on said carriage assembly above said motor driven roller pair, and spaced apart discs on each of said shafts, said discs on one of said shafts protruding into the spaces between said discs on the other shaft, said shafts and discs being positioned to engage the flattened tubular foil fed from said roller pair from opposite sides, give the foil a wave shape and guide the foil towards and through the slot in said bag supporting means.
