15-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 15 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. 15-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.Under stack roller – for placing of alternate stack of veneer near glutinous roll machine.

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

3.Glutinous roll machine – 4-roll with dosing rolls and glue circulation system.

4.Circular transporter – for veneer feed from glutinous rolls to sheet assembling table.

5.Sheet assembling table – lifting hydraulic table, on which manual assembly of sheets is performed with subsequent transfer of the stack on the transporter of pre-press load.

6.Under stack conveyor – for veneer supply to sheets assembly table. Capacity – 2 tons.

7.Under stack tables – for veneer stack and transport pallets for pre-pressing of stack of sheets.
