Briefly, a variety of embodiments of composite materials including part fabrication using composite materials is described.

A cable tie tensioning and severing tool includes: a cutting member, a pulling member with a pivotable pushing block abutting against the cutting member, a trigger with a stop block abutting against the pushing block, a pivotable pressing hammer, a turning knob, and an elastic member compressed between the pressing hammer and a spirally ramped end face of the turning knob such that the pressing hammer applies to the cutting member a pressing force whose magnitude can be adjusted by rotating the turning knob. The stop block can be driven by the trigger to push the pushing block, which in turn pulls a cable tie through the pulling member and, once the pressing force is overcome, pivots the cutting member to sever the cable tie.

In regard to at least one of long separator sheets (12a, 12b), measurement is carried out to measure the amount of curl at an edge of the at least one of the long separator sheets (12a, 12b) while applying tension to the at least one of the long separator sheets (12a, 12b) in the lengthwise direction (MD) of the at least one of the long separator sheets (12a, 12b), the edge being parallel to the lengthwise direction (MD) of the at least one of the long separator sheets (12a, 12b). This makes it possible to provide a method of measuring the amount of curl in a separator, a slitting apparatus, and a curl amount measuring apparatus, each of which is capable of carrying out a highly accurate nondestructive measurement of the amount of curl without having to cut a sample from a long separator sheet.

To easily specify the position of a defect in a separator, a method for producing a separator original sheet (12b) includes the steps of: forming a separator original sheet (12b) including a separator original sheet (12c) and a heat-resistant layer coated on the separator original sheet (12c); detecting a defect (D) in the separator original sheet (12b); and recording information including information on a position of the defect (D) which position is a position in the width direction of the separator original sheet (12b).

A dunnage conversion machine converts a sheet stock material into a dunnage product that is relatively thicker and less dense than the stock material. The conversion machine includes a conversion assembly that draws the sheet stock material therethrough and randomly crumples at least a portion of the sheet stock material. Before severing a discrete dunnage product of a desired length from the substantially continuous length of sheet stock material, the random crumpling is minimized or eliminated in an area to be cut to reduce or eliminate the production of scrap shards of sheet stock material during the cutting operation.
