  • Apparatus and method of producing rolls of bags
    Patent number: 6761329
    Abstract: In an apparatus and a method of producing a roll of bags, a bag feeding device is arranged to feed bags one by one to a winding device. The winding device includes a rotating spindle which is arranged to engage with each bag separately to wind the bag on it, so as to build a roll of bags in which the bags are unconnected to one another yet firmly held together. The winding device comprises at least two separate winding stations, each winding station being connected to one or more bag feeding devices; and a switch that is arranged upstream of a bag feeding device to direct the bags from one winding station to the other when a roll of bags has been completed in one of the winding stations.
