On the opposite side to the coating material unit RI, a coating material unit R0 is provided, the coating material of which has already been removed. The coating material unit R0, like the other coating material units R1-R4, is still received on the receiving device 11, but the coating material unit R0 can be removed from the receiving device 11 on occasion.
- the transport device 30 comprises a first pair of rollers 31, a second pair of rollers 33 and a third pair of rollers 34, the first pair of rollers 31 being provided closest to the storage device 10 in the transport direction of the coating material B1 and thus serving to introduce the coating material.
- a transfer (or insertion) of the coating material B1 from the coating material unit RI can take place manually or by means of a device such as a robot.
- a drive roller 32 (first drive mechanism) is provided with which the coating material is conveyed in the transport direction.
- a counter-pressure roller (not shown) can optionally be provided so that the coating material passes through a conveying gap formed between the drive roller 32 and the counter-pressure roller.
- a joining device 20 is provided which is set up to join end sections of successive coating materials to one another.

- the end of the coating material B1 is conveyed further through the transport device 30. Since the spring 12 presses the coating material units in the direction of the holder 13, when one end of the coating material unit RI is reached, this first coating material unit RI disengages from the holder 13 and is guided by the spring 12 along the receiving device 11 into a position similar to that of the coating material unit R0 will. The coating material unit R0 is pushed through the coating material unit RI. In the course of this, a second coating material unit R2 comes into contact with the holder 13.
- the coating material B2 provided on the second coating material unit R2 is transferred to the first roller pair 31 manually or by means of a device such as a robot (not shown) and comes into engagement with the first drive roller 32.
- the first drive roller 32 thus pulls the second coating material B2 from the second coating material unit R2 and conveys the second coating material B2 into the area of the joining device 20.
- This feeding of the coating material takes place in such a way that the first coating material B1 (or an end section thereof) is still in the joining device 20 is arranged, while the second coating material B2 is introduced into the joining device 20.
- the joining device 20 can now perform a connection / joining of the first and second coating material B1, B2 in order to thus produce an endless coating material.
- the joining device 20 is also set up to detect the position of the connection area between the first and second coating material B1, B2 and to pass this information on to the coating device.
- the coating device then adjusts the operation in such a way that the connection area is not used as a coating material for a workpiece, but is separated by a trimming unit.
- a pushing device 12 which is set up to push the material units R0-R4 received on the receiving device 11 in the direction of a holder 13.
- the receiving device can also be aligned in the vertical direction, so that the material units are pressed against a holder by gravity.
