PRINTING PLANE

 
There are 2 alternative constructions, either in anodized aluminium, for light-weight pieces ( thin glass ), or in bi-laminated wood ( thick glass ).

LIFTING OF SQUEEGEE & SCRAPER

 
For loading and unloading the printed pieces, and to clean the silkprint screen, the lifting is done in a hatch opening mode, by means of a PLC-controlled pneumatic drive. The machine is provided with hydraulic suspension to improve the lowering control. The operator can at any time adjust the lowering or lifting speed.
 

THICKNESS OF PRINTED PIECES

 
In the standard version the machines allow printing pieces up to 15 mm thick. On request, further thickness allowance can be provided for.
