Abstract
The invention relates to a method of producing coils of sheet metal consisting in coiling the sheet metal (1) following a hot-rolling, cold-rolling or cleaning operation. The inventive method is characterised in that it comprises the following steps, namely: coiling a part of said sheet metal (1) fixing a spacer (2) to one edge of the non-coiled part of the sheet metal (1) and coiling the rest of the sheet metal (1), thereby creating a coil (7) comprising a space (6) between two of the wraps thereof, with the possibility of fixing said spacer (2) either with or without interrupting the coiling; said coil (7) is then disposed in a heat treatment installation; a heat measuring device (8) is inserted in the space (6) created between the wraps of the coil (7) which is fitted with a spacer (2); the coil (7), which is fitted with a heat measuring device (8), is subsequently heat treated. The invention also relates to a spacer that can be used in order to implement said method.
