A screen printing machine hving a material conveyor driven by a power source, such that it is able to convey the material (3) to and to come to a halt at a printing position, in which print corresponding to the pattern on a stencil may be applied to the material, in addition to which the material conveyor is so affected by the power source that the material conveyor is driven at a high speed which, before the printing position for the material is reached, is reduced to a low speed so that the material is slowly advanced to its printing position. The front edge (3c min ) or similar of the material is capable of being sensed as it assumes a pre-determined position by means of a registration device (20,22) which does not touch the material, so that the material may be caused to stop by activation of the registration device. |
