Method and device for stringing substrates together in coating systems

A method for stringing together objects in a transport system and for adjusting an adjustable distance between two of the objects, wherein the two of the objects comprise a rear object arranged behind front object, wherein the front object moves at a speed in the transport system defined as a process speed vp, and wherein the adjustable distance between the rear object and the front object is initially an undefined distance, the method comprising the following steps:

• (a) accelerating a speed of the rear object to an initial speed vx, wherein vx>vp;
• (b) detecting a driving torque of at least one motor of the transport system;
• (c) detecting an increase in the driving torque when the rear object moves against the front object;
• (d) delaying the rear object by a predetermined value in order to establish that the adjustable distance between the front object and the rear object is a predetermined distance ap;
• and
• (e) adjusting the speed of the rear object to correspond to the process speed vp of the front object.
