Abstract
A filter bag assembly for a juice press is assembled from a unitary sheet of fabric and at least one coupling member and/or belt. The fabric sheet is foldable along a transverse fold line and then along left and right fold lines to form a seamless bag having left and right side margins each having four sheet layers. A left coupling member may be arranged to gather at least two of the four sheet layers of the left side margin, and a right coupling member may be arranged to gather at least two of the four sheet layers of the right side margin. Each belt connects the left side margin to the right side margin. Preformed holes in the fabric sheet are positioned to allow the coupling members and belt(s) to be installed to retain the folded bag. The assembled bag is inexpensive and the fabric sheet is replaceable.

A filter bag assembly comprising:
- a unitary sheet of fabric foldable along a transverse fold line and then along a left fold line and a right fold line to form a seamless bag, wherein said seamless bag has a left side margin and a right side margin, each side margin having four sheet layers;
- and at least one belt connecting the left side margin to the right side margin.
A filter bag assembly comprising:
- a unitary sheet of fabric foldable along a transverse fold line and then along a left fold line and a right fold line to form a seamless bag, wherein the said seamless bag has a left side margin and a right side margin, each side margin having four sheet layers;
- and
- coupling means for connecting at least one sheet layer of the left side margin to at least one sheet layer of the right side margin.
A method of assembling a filter bag for use in a juice press, the method comprising the steps of:
- providing a sheet of fabric having a plurality of belt holes;
- providing at least one belt;
- folding the sheet of fabric along a transverse fold line;
- folding the sheet of fabric along a left fold line generally perpendicular to the transverse fold line to form a left side margin having aligned belt holes;
- folding the sheet of fabric along a right fold line generally perpendicular to the transverse fold line to form a right side margin having aligned belt holes;
- inserting a left end of the at least one belt into the aligned belt holes in the left side margin;
- and
- inserting the right end of the at least one belt into the aligned belt holes in the right side margin.
