An activation furnace for activating a fiber sleet having carbonized yarn filaments includes a horizontal activation enclosure containing a heater, an inlet section and an outlet section through which the fiber sheet travels. A supply of oxidizing gaseous fluid is provided within the enclosure, that further includes one heat treatment zone and, at opposite ends of the enclosure, a temperature-raising zone and a temperature-lowering zone. The inlet and outlet sections are fitted with airlocks connected to cooling and suction devices.

Furnace for activating a woven or non-woven textile sheet based on

A method of activating a fiber sheet comprising carbonized filaments or spun carbonized yarn includes causing the sheet to travel horizontally through a furnace including at least one horizontal heat treatment zone in which there is maintained a regular and uniform temperature lying in the range of 800.degree. C. to 1000.degree. C. at a linear speed lying in the range 1 to 5 cm/min. over the length of the heat treatment zone and maintaining at least in the zone a constant flow of an oxidizing gaseous fluid that is uniformly distributed therein and at a pressure close to atmospheric pressure. A temperature-raising zone and a temperature-lowering zone are located at opposite ends of the treatment zone relative to the travel direction of the sheet and inlet and outlet sections of the treatment zone are fitted with air locks having cooling and suction systems.
