Elements The major elements of the screen change module are:
• The Chase C Casting
• Chase Right Hand Rail Assembly
• Chase Left Hand Rail Assembly
• Screen at Centre Sensor - Transmitter and Receiver
• Screen Depth Adjuster
• Web Assemblies (4 positions)
Operation The front cover is opened to gain access to the chase. The pneumatic push
buttons located on the underside of the front left and right hand web assemblies
are operated, releasing all four web assemblies on the front and rear linear ball
bush shafts. Releasing the web assemblies allows the user to adjust the
position of the chase left and right hand rail assemblies, to accommodate for
the appropriate size screen. The depth adjuster is set for either front or centre
justified screen image. The screen is loaded from the front of the machine and
slid into the machine along the top of stencil support plates. Three stencil
location leaf springs located in the right hand chase rail assembly ensure that
the screen is held in the correct location for printing, against the stencil guide
strips on the left hand chase rail assembly. The screen is pushed toward the
rear of the machine until it reaches the screen stop on the screen depth adjuster.
The user selects Screen Change, the four flap assemblies on each chase rail
assembly operate, clamping the screen to the stencil support plates.
