Abstract
Rotogravure cylinders used for printing on packaging materials based on the transfer of ink onto the packaging material from the printing cylinder surface with a printing technique. The lightweight rotogravure printing cylinders developed are not heavy which prevent the factors which pose an ergonomic risk in terms of occupational health and safety and also cause an increase in logistics costs. For this purpose, the wall thickness of the steel body of the cylinder is decreased.
Claims7
A lightweight rotogravure printing cylinder comprising:
- at least one body which has a hollow cylindrical form and inlets at both ends of the lateral surface of the cylindrical form that are open so as to allow access to the inner volume, and wherein
- at least one cover which enables to close the open inlets of the cylindrical body and to form a closed cylindrical form,
- at least one shaft opening that allows grasping the shaft which enables the cylindrical body to be placed on the printing machine and rotational movement to be transferred therethrough, when it is passed through the center of the cylindrical body;
- and
- at least one rib in the form of a circular plate which is spaced apart along the length of the cylindrical body extending between the covers, and enables the middle section of the cylindrical body remaining between the at least one cover to be supported from its inner surface, and has a shaft opening of a size that allows the shaft to pass through the center thereof.
