In electronics manufacturing, it is conventional to print a film onto a substrate (1) and then fire it in a continuous oven. A sequence of substrates is fed through the continuous oven on a conveyor belt (9). In order to fire substrates, even substrates printed on both sides, without damaging the films, the apparatus of the present invention employs wedge-shaped holders (5) which support each substrate only at its edges. The holders are secured to the belt (9) by securing shafts (15) which pass through loops or voids in the mesh belt. The shafts are preferably secured by a securing wire (17) passed through them. Wire (17) is kept from pulling out by an eyelet (19). In this manner, even substrates printed on both sides can be fed to the continuous oven without damage.
