Abstract: The invention provides a fibre cloth inspecting method for inspecting a fibre cloth regarding sparse density, filament break, various kinds of mark, fabric runs, break, weaving validation, and dyeing uniformity. The method includes following steps: scanning the fibre cloth by a scanning light beam; retrieving a light pattern generated by the scanning; generating an inspecting result information according to the light pattern in relation to the fibre cloth; and analyzing the fibre cloth regarding sparse density, filament break, various kinds of mark, fabric runs, break, weaving validation, and dyeing uniformity according to the inspecting result information.

Abstract: The invention provides an equipment of inspecting thickness of fibre cloth and method therefor. The method includes following steps: disposing a fibre cloth on a metal backboard; sensing an eddy current responding from the fibre cloth and the metal backboard by an eddy current sensing device to obtain a multilayer thickness information; and comparing the multilayer thickness information with a single-layer thickness information to obtain a cloth thickness information corresponding to the thickness of the fibre cloth, wherein the single-layer thickness information is obtained by sensing an eddy current responding from the metal backboard, thereby the thickness of fibre cloth can be obtained.

Abstract: A hole puncher with a quick disassembling structure for changing cutters comprises a pair of corresponsive extendible tongs handles, at least two cutters, and two quick disassembling structures; wherein each quick disassembling structure having an elastic clamp which is a small bent wire comprised of a fixed section, a latch section, and a control section, and such elastic clamp is mounted on the backside of the tip of the puncher by a fixture, and the cutter passing through a cutter hole is fixed by the latch section.
