Abstract:
Apparatus for producing a continuous rod (10) with an outer wrapper (12), the outer wrapper (12) being fed continuously as a material strip, and the material rod (11) which is to be wrapped resting on a driven forming belt (15) and being moved past forming beds (19) which, during transit, deform the outer wrapper (12) and material rod (12) to form the continuous rod (10), the forming belt (15) resting against the forming bed (19) with sliding action, which comprises the forming belt (15) resting against a heat-dissipating intermediate layer which is arranged between the forming belt (15) and the forming bed (19) and abuts against the forming bed (19), and wherein the intermediate layer is a heat-dissipating compensating belt (21) which is driven by a separate drive roller (25), other than the drive roller used to drive the forming belt and in the same direction, but at reduced speed with respect to the forming belt (15) whereby there is friction between the forming belt (15) and the compensating belt (21), and between the compensating belt (21) and the forming bed (19).
