## Abstract

The invention relates to method and apparatus for lining the cathode of the electrolytic cell. The method comprises filling the cell's shell with powder material, leveling it with a rack, covering the fill material with a dust-proof film, and compaction. Compaction is performed in two stages: preliminary static and final dynamic treatment by consequent movement of static and dynamic work tools of compaction along the longitudinal axis of the cathode of the electrolytic cell through a cushion, which is made of at least 2 layers: a lower layer, which prevents pushing powder material forward in the direction of travel, and an upper layer, which provides for a coupling between the cushion and the static work tool. Static treatment unit of the apparatus is designed in the form of a roller with a drive, connected to a dynamic treatment unit with a vibratory exciter by means of elastic elements.

## Claims

### Claim 1

An apparatus for forming seamless lining layers in electrolytic cells comprising:
a static treatment unit comprising a roller and a drive and
a dynamic treatment unit with a vibratory exciter mounted thereon,
wherein the dynamic treatment unit is connected to the static treatment unit by a plurality of elastic elements, the plurality of elastic elements comprising at least one vertical elastic element and at least one horizontal elastic element, providing for a simultaneous movement of the dynamic treatment unit relative to both the horizontal and vertical axes of the roller, such that vibration from the vibratory exciter to the static treatment unit is dampened in both the vertical and horizontal directions by the plurality of elastic elements.

### Claim 2 (depends on 1)

The apparatus of claim 1, wherein the plurality of elastic elements comprise rubber.

### Claim 3 (depends on 1)

The apparatus of claim 1, wherein the plurality of elastic elements comprise metal springs.

### Claim 6 (depends on 1)

The apparatus of claim 1, wherein the drive comprises a gear motor and a chain gear, the chain gear in connection with the roller, whereby rotation of the gear motor is transmitted to the roller via the chain gear.

### Claim 7 (depends on 1)

The apparatus of claim 1, wherein the dynamic treatment unit further comprises one or more piezoelectric sensors to monitor vibratory acceleration of the dynamic treatment unit.

### Claim 8 (depends on 1)

The apparatus of claim 1, wherein the dynamic treatment unit further comprises a rocker arm in connection with the plurality of elastic elements.

### Claim 9 (depends on 1)

The apparatus of claim 1, wherein the vibratory exciter exhibits a circular driving force.

### Claim 10 (depends on 1)

The apparatus of claim 1, wherein the vibratory exciter exhibits a linear driving force and is mounted on the dynamic treatment unit at an acute angle to the treated surface.
