## Abstract

A workstation of a packaging machine comprises a lifting device (100) which is configured such that it is able to convert a rotary motion of a motor (8) into a translatory motion of the workstation by means of a lever device (6). It is the object of the present invention to provide in improved lifting device. The stroke of the lifting device (100) is performable for this purpose by a pivotable lever (61) and a roller (32) which cooperates with an upper roller limit (33).

## Claims

### Claim at position 1

1-14. (canceled)

### Claim 15

A workstation of a packaging machine, the workstation having a lifting device comprising:
a motor;
a lever device that includes:
a pivotable lever;
a roller; and
an upper roller limit, which cooperates with the roller to perform a stroke of the lofting device,
wherein rotary motion of the motor is converted into a translatory motion of the workstation by means of the lever device.

### Claim 16 (depends on 15)

The workstation according to claim 15, wherein the upper roller limit is partially uneven.

### Claim 17 (depends on 15)

The workstation according to claim 15, wherein the pivotable lever is pivotable at least about 360°.

### Claim 18 (depends on 15)

The workstation according to claim 15, wherein the lever device is structured and arranged eccentrically such that a tilting moment is reducible during lifting of the workstation.

### Claim 19 (depends on 15)

The workstation according to claim 15, further comprising a second lever device, the two lever devices being structured and arranged such that a tilting moment is omitted.

### Claim 20 (depends on 15)

The workstation according to claim 15, further comprising a lower roller limit.

### Claim 21 (depends on 20)

The workstation according to claim 20, wherein the roller is located between the upper roller limit and the lower roller limit and/or between the lever (61) and a lever opposite part (61a).

### Claim 22 (depends on 19)

The workstation according to claim 19, wherein the roller is located between the two lever devices.

### Claim 23 (depends on 15)

The workstation according to claim 15, further comprising a lid, wherein the lid opens a chamber of the packaging machine, the lid being raiseable from a lower position wherein a chamber is closed to raised position wherein the chamber is opened.

### Claim 24 (depends on 15)

The workstation according to claim 15, wherein the workstation is a moulding station and/or a sealing station and/or a cutting station.

### Claim 25 (depends on 15)

The workstation according to claim 15, wherein the packaging machine is a deep drawing machine and/or a tray closing machine.

### Claim 26

A workstation of a packaging machine, the work station having a lifting device comprising:
a motor; and
a lever device that includes a pivotable lever and a connecting rod to perform a stroke of the lofting device;
wherein rotary motion of the motor is converted into a translatory motion of the workstation by means of the lever device.

### Claim 27 (depends on 26)

The workstation according to claim 26, further comprising a lid, wherein the lid opens a chamber of the packaging machine, the lid being raiseable from a lowered position, wherein a chamber is closed, to a raised position, wherein the chamber is open.

### Claim 28 (depends on 26)

The workstation according to claim 26, wherein the workstation is a moulding station and/or a sealing station and/or a cutting station.

### Claim 29 (depends on 26)

The workstation according to claim 26, wherein the packaging machine is a deep drawing machine and/or a tray closing machine.
