Abstract
In a stencil printer system, a stencil is made by the use of master material unrolled from a stencil material roll and is wound around a printing drum by clamping the leading end of the stencil on the printing drum and rotating the printing drum while the stencil is once slackened on the way to the printing drum. There is provided along the stencil conveyance path between the stencil material roll and the printing drum a tension blade which is pressed against the stencil to apply back tension to the stencil when the stencil is run by the printing drum and the tension blade is formed so that the stencil undergoes force which tends to displace outward the stencil from the central portion in the direction of width of the stencil.
