Abstract
A master making device incorporated in a stencil printer. The operation for feeding the leading edge of a web or stencil toward a master clamper provided on a print drum is assigned to a platen roller. When the web is to be wrapped around the print drum, the operation for causing the web to form a slack and the operation for applying a tension to the web are implemented only by a tension member which selectively blocks or unblocks a web passageway.
