In a sheet shipping container of the type having a pair of elongated members in spaced relation to one another in the container, each of the members having at least one slot for receiving edge portion of the sheet wherein the sheet is acted on by transportation forces which displace the sheet along a path generally transverse to longitudinal axis of the members the improvement comprising:
- means mounted in the at least one slot of at least one elongated member and compressed between the walls of the at least one slot and adjacent sheet portion for applying a biasing force on the sheet portion to prevent displacement of the sheet due to the transportation forces.
A sheet shipping container wherein the sheet to be shipped is acted on by transportation forces which shift the sheet, comprising:
- a pair of elongated members of which at least one of said members is made of compressible, resilient material having at least one slot formed therein to apply a biasing force on sheet portion therein to prevent shifting of the sheet by the transportation forces;
- and
- means for mounting said members in spaced relation to one another.
A method of shipping at least one sheet, comprising the steps of:
- mounting edge portion of a sheet in a slot formed in each of a pair of spaced elongated members;
- while
- applying a biasing force to sheet portion in at least one of the slots to prevent displacement of the sheet during shipment thereof.
