Abstract
In a duplicating machine, a system for readily interchanging a printing head on a permanent rotatable shaft of a printing couple of the machine, to facilitate rapid changing of printed indicia in short run duplicating situations. An elongated manually manipulatable segment is readily removably mountable on the rotatable shaft. At least one ring-like mounting member is fixable to the manually manipulatable segment at any position therealong. At least one adjustable printing head is secured to the mounting member. The manually manipulatable segment can be bodily removed from the shaft and the printing head can be replaced or adjusted while the machine continues to operate.

In a duplicating machine, a system for readily interchanging an adjustable printing head on a rotatable shaft of a printing couple to facilitate rapid changing of printed indicia in short run duplicating situations, comprising:
- an elongated manually manipulatable segment readily removably mountable on said rotatable shaft and extending axially along the shaft substantially the entire width of the printing area of the printing couple;
- at least on mounting member fixable to the manually manipulatable segment at any longitudinal position therealong;
- and
- at least one adjustable printing head secured to the mounting member,
- whereby the manually manipulatable segment can be bodily removed from the shaft, and the printing head can be replaced or adjusted with the segment removed while the machine can continue to operate.
In a duplicating machine, a system for readily interchanging an adjustable printing head on a rotatable shaft of a printing couple to facilitate rapid changing of printed indicia in short run duplicating situations, the improvement comprising an elongated, generally semi-cylindrical manually manipulatable segment having an opening extending lengthwise thereof and of a width at least equal to the diameter of the shaft for readily removably mounting the segment on the shaft in a direction transverse thereto, the elongated manually manipulatable segment extending axially along at least fifty percent of the length of the shaft, and a mounting member fixable at any longitudinal position along said segment for mounting at least one said printing head whereby the segment can be bodily removed from the shaft, and the printing head can be replaced or adjusted with the segment removed while the machine can continue to operate.
In a duplicating machine, a system for readily interchanging an adjustable printing head on a rotatable shaft of a printing couple to facilitate rapid changing of printed indicia in short run duplicating situations, comprising:
- a manually manipulatable segment readily removable mountable on said rotatable shaft and extending axially along the shaft substantially the entire width of the printing area of the printing couple;
- at least one mounting member fixable to the manually manipulatable segment at any longitudinal position therealong;
- at least one adjustable printing head secured to the mounting member, whereby the manually manipulatable segment can be bodily removed from the shaft, and the printing head can be replaced or adjusted with the segment removed while the machine can continue to operate;
- and
- safety latch means for holding the manually manipulatable segment on the shaft automatically in response to mounting the segment in proper position on the shaft.
In a duplicating machine, a system for readily interchanging an adjustable printing head changing of printed indicia, the improvement comprising an elongated manually manipulatable segment positionable on said shaft, and extending axially along the shaft substantially the entire width of the printing area of the printing couple, quick-release latch means for readily removably securing the segment on the shaft, and a mounting member fixable at any position lengthwise along the segment for mounting at least one said printing head whereby the segment can be bodily removed from the shaft, and the printing head can be replaced or adjusted with the segment removed while the machine can continue to operate.
