A System for Adjusting Positions of Rollers in An Outsert Making Machinery

A system (100a, 100b, 100c, 100d, 100e, 100f) for adjusting positions of grooving rollers (21) in an outsert making machinery (200), the machinery (200) includes a strip making unit (10′) adapted to make a strip (13′) from a paper (12) using a first set of rollers (11′) therein, one or more folding units (14a′, 14b′) adapted to cross fold the strip (13′) by one or more folding rollers (or folding knives) (15a′, 15b′) therein, a grooving assembly (20) having grooving/gripping rollers (21) positioned between the strip making unit (10a) and the folding units (14a), the grooving assembly (20) is mounted to the strip making unit (10′) for receiving the strip (13′) therefrom, the grooving rollers (21) are operated to make grooves (23′) on the strip (13′), the system (100a, 100b, 100c, 100d, 100e, 100f) characterized in that:

• an input interface (30) for receiving input data such as length and thickness of the strip (13′), number of cross folds to be made on the strip (13′) and geometrical specifications of an outsert (16′);
• a work station (40) connected to the input interface (30), the work station (40) includes a processor (50) which calculates output data in the form of geometrical details of the grooving rollers (21) (or gripping rollers), the position of the grooving rollers (21) from the first reference (21a), a combination of grooving rollers (21) on the grooving shaft (22) and a sequence of combinations of grooving rollers (21) on the grooving shaft(s) (22) required for enabling the grooving rollers (21) to make grooves (23′) on the strip (13′) according the input data provided through the input interface (30) and also deriving operational parameters of the folding units (14a′, 14b′) for enabling the folding units (14a′, 14b′) to fold on the grooves (23′);
• a display (60) connected to the processor (50) which displays the output data calculated by the processor (50);
• and
• wherein the grooving rollers (21) (or gripping rollers) are adjusted manually according to the output data from the display (60) or by operating a first position adjusting mechanism (70) of the system (100);
• and the operational parameters of the folding unit (14a′, 14b′) are adjusted manually or by a control unit (80) connected to the folding unit (14a′, 14b′).
