Presses are used for compressing flat workpieces during solidification of the glue.
Hand Screw Press
This press serves for coating flat workpieces and for similar operations.
The frame made of sectional steel is bolted. Cross members on the bottom beams cary the press table (sometimes the press table is retractile).
Between the upper beams there are flanged cross bars with threads for transmitting motions for the screws. At the lower end of the screw the pressure shoe is supported. By means of the press plate forming the lower end of the pressure shoe a uniform force transmission is obtained.
Information on labour safety
The pressure elements require a safety guard, they are to be secured against unintended lowering.
Recommendations for maintenance
Make sure that the points of support are regularly lubricated. Immediately remove impurities, especially those of the press plates. Regularly apply parting compounds on the press plate to prevent sticking of glue residues.
