Abstract: A magnet roll for the toning of electrostatic latent images comprising a central rectangular core mounted to be rotatable about an axis through an angle of about 180.degree. from a first to a second position and carrying face magnetized permanent magnet segments on one rectangular face thereof, and a non-magnetizable cylindrical hollow shell mounted coaxially with the core and adapted to rotate about the axis of the core to allow the face magnetized permanent magnet segments to be moved to a first position to face a member containing an electrostatic latent image on the surface thereof during toning of the electrostatic latent image but rotatable to the second position whereby a magnetic toner carried on the cylindrical hollow shell is removed from the surface of the cylindrical hollow shell in the toning position.

Abstract: The method of and means for the production of markers for the cutting of fabric or material in the garment or allied industries comprising forming a latent electroscopic image pattern on the surface of a dielectric master and toning the image with a primary toner and transferring the primary image toner to a conductive receiving member and fixing and then toning the fixed image with a secondary toner and transferring optionally to the fabric or material or to multiple copy members for marking fabric or material.
