20-storey press

Composition of press with pressing mechanization and pre-press with mechanization of loading and unloading operations

1. Transporter of loading and unloading - for receiving of a stack of sheets and simultaneous pre-press unloading and loading.

2.Pre-press (force – 5000kN, individual pump hydraulic drive)

3.Output roller – for receiving a stack of pre-pressed sheets and their supply to the lifting table.

4.Lifting hydraulic table – for lifting of sheets stack to the level of supply of top sheet to shelving loading mechanism.

5. Shelving loading mechanism – for storey-loading of shelving.

6. Shelving – for horizontal transportation to the press and subsequent (simultaneously) loading of 20 storeys of press.

7.Lifting mechanism of shelving – for storey vertical movement of shelving during its loading.

8.Loader – for partial ejection of pressed plywood from the press after its opening and subsequent loading of press.

9. Rail track and current feeder – for moving shelving to the press and lifting mechanism of shelving.

10.Service table – to provide access to the upper floors of press if it is necessary to tear off plywood glued to the plate.

11. 20-storey hydraulic press (force - 6300 kN, individual pump hydraulic drive).

12. Discharge device – for storey discharging of press.

13.Under stack roller – for receiving a stack of plywood from discharging mechanism and its subsequent transportation by means of workshop mechanization.

Composition of section of sheets assembly

1. Receiving conveyor (2 pcs)– for placing of alternate stack of veneer near glutinous roll machine.

2.Under stack lifting table (2 pcs) – for veneer stack lifting on the level of supply to glutinous roll machine.

3.Glutinous roll machine (2 pcs) – 4-roll with dosing rolls and glue circulation system.

4.Circular transporter (2 pcs) – for veneer feed from glutinous rolls to sheet assembling table.

5.Sheet assembling table (2 pcs) – lifting hydraulic table, on which manual assembly of sheets is performed with subsequent transfer of the stack on the transporter of longitudinal and cross feed.

6. Transporter of longitudinal and cross feed – for receiving a stack of sheets from two assembly tables and subsequently feeding on the pre-press conveyor.

7. Under stack conveyor (2 pcs) – for veneer supply to sheets assembly table. Capacity – 2 stacks

8. Under stack tables (5 pcs) – for veneer stack and transport pallets for pre-pressing of stack of sheets
