Abstract

The method of removing printing press rollers or cylinders, and a removal mechanism for use therein in extracting relatively heavy printing press rollers from very restricted and confined locations. The method comprises affixing to the frame of the press a pair of removal mechanisms, one at each end of the press. Each such mechanism comprises a mounting bracket including clamping means, a winch and an extension having an opening through which the winch line extends. The extension rests against the topmost rollers and the line is extended into the center of the press to be wrapped about the respective end of the roller to be removed. Simultaneous operation of such winches causes the roller to be lifted from its bearings or journal, thereafter to be lowered by means of the winches for manual removal.

Claims4

Dependent claims

A handling mechanism for handling a printing press roller comprising in combination,

a frame,
a support for said frame formed with a generally vertically disposed leg and a generally horizontally disposed leg for ready attachment and removability to a structural member of a printing press,
said frame comprising an extension fixed to said vertical leg of said support and forming an obtuse angle therewith to engage a pair of press rollers when said support is attached to said structural member,
mounting means on said extension and positioned between said extension and said support and comprising a generally horizontal mounting pad,
and a winch secured to said mounting pad and having a line which is directed generally horizontally toward said extension and thereby being coupled to a printing press roller for handling thereof and also provide the effect that a pulling force on said line exerts a force on said pair of press rollers.
