Abstract
A process and apparatus for prestretching screen fabric usable in screen printing allows desired screen tension to be achieved rapidly when the screen fabric is inserted into a screen printing frame. The screen fabric is tensioned using a tensioning device, and subsequently an alternating load is applied to the screen fabric to prestretch it. The loading may be applied along a direction parallel to, perpendicular to, or at an intermediate angle to the plane of the screen fabric.
Claims23
A process for prestretching screen fabric usable in screen printing, comprising the steps in order of:
- tensioning said screen fabric to be used in screen printing;
- and
- applying an oscillatory alternating load to said tensioned screen fabric to prestretch said screen fabric.
An apparatus for prestretching screen fabric usable in screen printing, comprising:
- a tensioning device attached to said screen fabric usable for screen printing, said tensioning device tensioning said screen fabric;
- and
- at least one vibrator, said vibrator vibrating said screen fabric as it is tensioned by said tensioning device to prestretch said screen fabric.
