Abstract

The invention relates to a litho laminating machine ( 10 ) having a frame ( 18 ), an accelerator table ( 20 ) mounted to the frame ( 18 ) so as to be pivotable around a pivot axis (P), a plurality of accelerator rollers ( 24 ) mounted on the table ( 20 ), and a motor ( 42 ) for driving the accelerator rollers ( 24 ), characterized in that the motor ( 42 ) is mounted to the frame ( 18 ), with a rotatable transmission element ( 30, 36 ) being mounted so as to have an axis of rotation which coincides with the pivot axis (P), both the motor ( 42 ) and the accelerator rollers ( 24 ) being connected to the transmission element ( 30, 36 ).

Claims (16)

1. A litho laminating machine comprising:

a frame;

an accelerator table mounted to the frame so as to be pivotable around a pivot axis;

a plurality of accelerator rollers mounted on the accelerator table;

a motor configured to drive the plurality of accelerator rollers, the motor being mounted to the frame; and

a rotatable transmission element mounted so as to have an axis of rotation which coincides with the pivot axis,

wherein both the motor and the plurality of accelerator rollers are connected to the rotatable transmission element.

2. The litho laminating machine of claim 1 , wherein the rotatable transmission element comprises a drive pulley, and the plurality of accelerator rollers are connected to the drive pulley by means of a belt drive.

3. The litho laminating machine of claim 2 , wherein the belt drive is a carbon belt.

4. The litho laminating machine of claim 2 , wherein the belt drive is a toothed belt.

5. The litho laminating machine of claim 2 , further comprising at least one tension roller.

6. The litho laminating machine of claim 2 , further comprising at least one intermediate pulley.

7. The litho laminating machine of claim 2 , wherein the rotatable transmission element comprises a driven pulley, and the motor is connected to the driven pulley by means of a belt engaging at a motor pulley.

8. The litho laminating machine of claim 7 , wherein a diameter of the motor pulley is larger than a diameter of the driven pulley.

9. The litho laminating machine of claim 1 , wherein the motor is an electric motor.

10. The litho laminating machine of claim 1 , further comprising a lifting mechanism configured to lift the accelerator table from an operating position to a maintenance position.
