Abstract
A coil of an interconnected chain of open bags is provided in which the coil has a center opening having a diameter at least as great as the transverse dimension of the bags. A dispenser is provided on which a coil of bags is mounted. An end of the chain is pulled from the center opening and fed around a tapered mandrel and thence over a feed control mandrel oriented in angular relationship with the tapered mandrel. The web is then fed to a bagging machine for dispensing, loading and closing of the bags. The table on which the coil is mounted is rotatable so that the orientation of a span of bags running from the coil to the tapered mandrel remains substantially constant as the web is fed.
Claims4
A process of dispensing an annularly coiled web of interconnected but open bags comprising:
- a) positioning the coiled web on a rotatable table and in concentric relationship with a tapered guide mandrel;
- b) feeding the web with the bags oriented closed end first, the feeding being from a central coil opening;
- c) reeving the web around the tapered mandrel and thence over a rotatable feed control mandrel;
- d) feeding and slightly twisting the web over a span between the feed control mandrel and a roll having an axis other than parallel with the feed control mandrel and thence to a load station;
- and
- e) the feeding and twisting over the span being performed to bring the transverse dimension of the web at the roll into parallelism with a bag at the load station.
