PCT No. PCT/DE93/00632 Sec. 371 Date Apr. 21, 1995 Sec. 102(e) Date Apr. 21, 1995 PCT Filed Jul. 16, 1993 PCT Pub. No. WO94/09408 PCT Pub. Date Apr. 28, 1994An electrographic printing or copying machine contains, by way of example, a preheating saddle (20,21) positioned upstream of a pair of fixing rollers in the recording substrate running direction and a braking element (10). The preheating saddle (20,21) and braking elements (10) form a gliding surface (23). Suction openings (18,19) in fluid communication with a vacuum-generating device ensure good contact between gliding surface (23) and recording substrate. With the aid of a valve (1), the vacuum can be matched to the operating parameters of the printing and copying machine, or to the parameters of the recording substrate.
