Abstract
A double-ended bag is formed from a tubular woven sheet having at least one tie member extending along the length of the tubular sheet. The tubular sheet is cut to create bag panels and tie member segments in registration. The bag panels are sewn together with the bag panels in registry and the tie member segments in registry.

A method of manufacturing a double-ended bag having first and second bag panels defining a bag interior and a bag opening at one end communicating with said bag interior, said bag additionally including first and second elongated flexible tie members located adjacent to said bag opening for selectively closing said bag opening, said method comprising the steps of:
- tubular weaving a sheet of flexible material to form an elongated tube comprised of woven warp and weft strands, said tube having a primary longitudinal axis;
- during said tubular weaving step, weaving into said strands said first and second tie members, said first and second tie members being spaced from one another and extending along a length of said tube in a direction parallel to said primary longitudinal axis;
- forming an elongated opening in said tube extending along the length of said tube in the direction parallel to said primary longitudinal axis and located between said first and second tie members;
- severing said tube and said first and second tie members along spaced lines of cut transverse to said primary longitudinal axis to divide said tube into separate tube segments and said first and second tie members into double-ended first and second tie segments, each tube segment comprising two bag panels, with each bag panel having a panel top end, a panel bottom end and two spaced panel side edges extending between the panel top end and the panel bottom end, and each panel having a tie segment connected thereto and woven therein;
- bringing the two bag panels together into substantial registration with the panel bottom ends forming a fold;
- substantially simultaneously with the step of bringing the two bag panels together, bringing the tie segments connected thereto into substantial registry;
- and
- sewing the bag panels together along the panel side edges thereof, with the two panel top ends being unsecured and forming said bag opening so as to form said bag additionally including first and second elongated flexible tie members located adjacent to said bag opening for selectively closing said bag opening.
