ABSTRACT:
A transport apparatus for boards or workpieces in board form, for example printed circuit boards which are to be coated with plastic, for example UV curable plastic, has advancing means for the transport of the boards and grippers or clamps for seizing the board edges during the transport and advancement of the boards. In order to avoid a risk of damaging the sensitive board surfaces, in particular when transferring the boards from one conveyor to the other, the gripper or grippers or clamps is/are attached to a holding element or rack, releasably coupled to the transporting or advancing means of the apparatus. This holding element remains connected, via its grippers to the board during the complete transport of the latter and can be transferred and reloaded together with the board held by it at transitions from one advancing means to another or from one processing station to the other. The handling of the boards is thus in practice directed instead to its holding elements and consequently the risk which this handling entails is kept away from the boards.
