Abstract
A plurality of injector elements are mounted on a frame and within a nozzle above a subjacent support for depositing a layer of pulverulent product on the support. In order to change the predetermined spacing of the injectors, they are selectively connected to a shuttle which is moved by a digitally controlled stepping motor to a predetermined position, after which they are separated from the shuttle. A solenoid mounted on each of the injectors can be activated to frictionally hold the injector at its predetermined position.
