Pelt board bag and an assembly of a pelt board bag and a pelt board

An intermediate product comprising a sheet of fat absorbing material for being further processed into a pelt board bag for use in combination with and applied externally to a pelt board for the tanning and drying of a pelt applied externally to the pelt board bag, the sheet of fat absorbing material comprising:

• first and second opposed longitudinal boundaries extending between a first end of the sheet and an opposite second end of the sheet and configured to be joined to each other, wherein the second end of the sheet is broader than the first end of the sheet;
• and
• a fold line extending between the first end of the sheet and the second end of the sheet, whereby, when the sheet is folded along the fold line, the first and second longitudinal boundaries are joinable to each other so that the sheet defines, in a first state, a flat two-layer structure, and in a second state, a tubular structure having an inner perimeter increasing from a first open end defined by the first end of the sheet to a second open end defined by the second end of the sheet wherein the fold line is defined by a folding feature selected from the group consisting of one or more of slits, oblong apertures, embossings, and score lines.

A pelt board bag configured to be applied externally to a pelt board for the tanning and drying of a pelt applied externally to the pelt board bag, the pelt board bag comprising a sheet of fat-absorbing material folded along a fold line extending between a first end of the sheet and an opposite second end of the sheet, the sheet having first and second opposed longitudinal boundaries extending between the first end of the sheet and the second end of the sheet and joined together to define, in a first state, a flat two-layer structure, and in a second state, a substantially tubular structure;

• wherein the pelt board bag, in the second state, defines an open top end and an open bottom end when the pelt board bag is used in combination with a pelt board, the bottom end being broader than the top end, the pelt board bag defining, in the second state, a perimeter that increases from the top end to the bottom end;
• and
• wherein the fold line is defined by a folding feature selected from the group consisting of one or more of slits, oblong apertures, embossings, and score lines, and folds.
