Abstract
A method and an apparatus for filling and transferring a bag while maintaining the extended tab of the bag slidingly secured on holding pins. A first bag from a plurality of juxtaposed bags is opened and filled while its extended tab is maintained stationary on holding pins. After the bag is filled, the bag is caused to be displaced on the holding pin to a bag tieing position. During the displacement of the bag to its tieing position, a neck portion is formed in the upper part of the bag and this neck portion is fed against an adhesive tape which is simultaneously secured about the neck portion as it is formed.
Claims10
A method of filling and transferring an open mouth bag, said bag having an extended tab above a mouth opening, holes in said tab for supporting said bag on holding pins, said method comprising:
- (i) holding said tab of a first bag to be opened from a plurality of juxtaposed bags,
- (ii) opening said mouth opening at a filling location,
- (iii) filling said bag with a product,
- (iv) releasing said tab to cause displacement of said first bag to a further location remote of said filling location while supporting said bag by said tab held by holding pins,
- (v) sealing said bag below said mouth opening to close said opening, and
- (vi) detaching said tab from said holding pins.
An apparatus for filling and transferring an open mouth bag, said bag having an extended tab above a mouth opening, holes in said tab for supporting said bag on holding pins, said apparatus comprising bag support means having two spaced apart elongated holding pins, said pins being aligned to be received in said holes of said tab, said pins being disposed to define a bag transfer section extending from a bag filling location whereby said bag is displaced to a sealing location remote of said filling location while supporting said bag by said holding pins extending through said holes in said tab, said bag transfer section having a downwardly extending section of said pins leading to said bag sealing location remote from said filling location.
A bag tieing apparatus comprising support means having two spaced apart pins extending in a common plane, said pins extending through a respective hole in an extended tab of a bag, said tab being disposed above a mouth opening of said bag, said pins converging toward one another to define a throat portion, attachment means located relative to said throat portion, means to displace said bag through said throat portion and into converging means to displace the side wall of said bag to converge to define a neck portion and feeding said neck portion into said attachment means to secure said neck portion.
