Abstract

A screen printing machine including a stencil sheet assembly having a frame member having outer peripheral sides for partitioning an outer configuration and inner peripheral sides for partitioning an opening and stencil sheet adhered to one face of the frame member to cover the opening, a tension frame projected to inner sides of the inner peripheral sides of the frame member, having a raised portion toward the stencil sheet and arranged on other face of the frame member for applying tension to the stencil sheet, and holding means for holding the tension frame and the stencil sheet assembly which are put together such that a front face of the tension frame in a direction of raising the raised portion and the outer face of the frame member are brought into contact with each other.

Claims

1. A stencil printing machine comprising:

a stencil sheet assembly having a frame member having outer peripheral sides for partitioning an outer configuration and inner peripheral sides for partitioning an opening, a stencil sheet adhered to one face of the frame member to cover the opening, and at least one folding groove portion parallel to at least one of the inner peripheral sides of the frame member formed on the other face of the frame member;

a tension frame projected to inner sides of the inner peripheral sides of the frame member, and having a raised portion raised toward the stencil sheet and arranged on the other face of the frame member for applying tension to the stencil sheet; and

holding means for holding the tension frame and the stencil sheet assembly which are put together such that a front face of the tension frame in a direction of raising the raised portion and the other face of the frame member are brought into contact with each other.
