Edging device for edging narrow sides of workpiece, has switching unit which switches heat source, when detected temperature exceeds predetermined threshold, so that temperature detector is provided with cooling device

摘要

The device has a workpiece feed device which supplies an edge tape (1) slightly warmed up by workpiece (4) workpiece along a supply path. A heat source (5) heats a detention-obtaining function layer of the edge tape. A pressure device (3) presses the narrow side of the workpiece. A temperature detector (2) is arranged in the effective range of the heat source. A switching unit switches the heat source, when detected temperature exceeds the predetermined threshold, so that temperature detector is provided with a cooling device.
