Publication Summary
An apparatus for sticking onto a screen plate a photosensitive laminated film obtained by forming a layer of a photosensitive agent on one surface of a base film, wherein a blade is provided on the front side of rollers that hold the photosensitive laminated film to press-adhere said photosensitive laminated film onto the screen plate. The tip of the blade presses the photosensitive laminated film onto the screen plate such that an angle is defined between the photosensitive laminated film and the screen plate to get rid of the air. Therefore, no bubbles are trapped therebetween.| Country | United States |

Apr. 22, 1988, now abandoned.
Claims
What is claimed is:
1. An apparatus for producing a printing stencil plate for screen printing
comprising:
a pair of rollers disposed so as to receive a photosensitive laminated film
passing in a predetermined direction therebetween and to feed the film; and
a blade extending upwardly and disposed at a front side of the rollers with
respect to the direction of the film for pressing the film onto a screen plate
to form an angle,
the angle of the blade being so defined that trapping of air between the film
and the plate is eliminated.
2. An apparatus for producing a printing stencil plate for screen printing
comprising:
a pair of rollers disposed so as to receive a photosensitive laminated film
passing therebetween in a predetermined direction and to feed the film;
a blade extending upwardly and disposed at a front side of the rollers with
respect to the direction of the film; and
a roller rotatably mounted at an upper end of the blade for pressing the film
onto a screen plate while eliminating the trapping of the air bubbles between
the film an...
