AI Technical Summary

Problems solved by technology

Vibration phenomena are also more severe and result in the need to use increasingly stronger springs to apply greater and greater tension, which further increases the mechanical stress on the chainset 80, thereby reducing its useful life and increasing failure or damage risks of

Embodiment Construction

[0019] It should be understood that throughout this text, the words "sheet" or "sheet-like element" or "sheet-like element" may refer very broadly to any sheet-like printing substrate, such as cardboard, paper, plastic sheet, etc.

[0020] figure 1 Shown is a stamping press for processing sheet metal. This processing machine 1 generally comprises several workstations arranged side by side but interdependent to form an integral assembly. Thus, there is an infeed station 100 , an infeed plate 200 , a platen processing device 300 , a waste discharge station 400 and a receiving station 500 .

[0021] figure 2 A conventional hot stamping machine is schematically shown. The feed station 100 is fed from a pallet 101 stacked with a plurality of sheets 10 such as cardboard sheets. The gripping members pick up the panels one by one from the top of the stack and convey the panels to the next infeed plate 200 . In some machines, the sheets are removed from the bottom of the stack. ...

Abstract

A machine for processing elements in sheet form, the machine having chainsets which move gripper bars for moving sheet elements through the machine. At least one tensioner device generates a tension force in the chainsets. The chainset tensioner device includes a drive member capable of generating a variable force, having an intensity dependent on the instantaneous production rate of the machine. Chainset wear is greatly reduced, and the life of the chainsets is lengthened considerably.

Description

technical field [0001] The invention relates to a machine for processing plate-shaped elements, said machine comprising a chain set tensioner. [0002] The invention can be applied particularly advantageously, but not exclusively, to the field of machines for processing paper or cardboard sheets for the manufacture of packaging. Background technique [0003] A machine for processing plate-like elements consists of a series of workstations, one of which may include a stamping press for processing sheet metal. [0004] In fact, it is common practice to carry out converting operations on paper or cardboard in machines for processing sheet-like elements. For example, the finishing operation may be a printing operation comprising printing of text and / or graphics by hot stamping, ie pressure coating of a colored or metallized film taken from one or more strips of hot stamping foil. The machining operation may also involve embossing or scoring, ie deforming the sheet to create a ...
