Abstract

Process for improving the maximal use of inking materials partic. in the printing appts. of equipment which treats information electronically, involves the unwinding of the inking material at a substantially constant speed onto the printing units. The printing appts. has an adjustable control for the inking material or special inking material which is pref. a material which allows a maximal use of ink >=30%/linear m over its entire length, e.g. nylon with 112 threads/cm2 and 34 individual fibres/thread. Process allows a higher and more regular use of ink than previous processes, thus reducing wastage. Pref. each end of the pref. inking material is tied to a spool which has exterior dia. d > half of the exterior dia. D of the roll made from the inking material wound on the spool. Inking material is so short that the use of the ink per linear metre deviates 10% from its maximal value over its entire length, e.g. d is pref. 40-60 mm and the length of the inking material is 6-12 m.

Description

"Verfahren zur verbesserten Ausnutzung "Process for Improved Utilization

von Farbtüchern" Die Erfindung betrifft ein Verfahren nach dem Oberbegriff des Anspruches 1. of colored cloths "The invention relates to a method according to the preamble of claim 1.

Bei der Verwendung von Farbtüchern auf bekannten Druckern hat sich gezeigt, daß die Farbausnutzung pro laufenden Meter einerseits vergleichsweise niedrig ist und andererseits über die Farbtuchlänge starken Schwankungen unterworfen ist.When using color blankets on known printers showed that the color utilization per running meter is on the one hand comparatively low and on the other hand is subject to strong fluctuations over the length of the ink sheet.

Mit der Erfindung wird das Ziel verfolgt, ein Verfahren zu schaffen, bei dem die Farbausnutzung höher und gleichmässiger ist als bisher.The aim of the invention is to create a method in which the color utilization is higher and more even than before.

Das gesetzte Ziel läßt sich durch die Lehre gemäß dem kennzeichnenden Teil des Patentanspruches 1 erreichen.The goal set can be revealed through the teaching according to the characteristic Achieve part of claim 1.

Zur Durchführung des erfindungsgemässen Verfahrens benötigt man entweder einen Drucker mit regelbarem Farbtuchantrieb oder besondere Farbtücher.To carry out the process according to the invention, either a printer with an adjustable ink sheet drive or special colored sheets.

Ein Farbtuch, mit dem sich gute Ergebnisse erzielen lassen, ist bei einem Außendurchmesser des Farbtuchkers von d = 40 -60 mm, vorzugsweise 6 - 12 m, insbesondere 9 m lang. Bei ihm ist nicht nur die Farbausnutzung gleichmässig, sondern es wird auch ein Schieflaufen des Farbtuches verhindert.A color cloth that can be used to achieve good results is with an outside diameter of the ink cloth of d = 40-60 mm, preferably 6-12 m, especially 9 m long. With him, not only is the use of color evenly, but also it also prevents the paint sheet from running incorrectly.

Die Wirtschaftlichkeit läßt sich dadurch steigern, daß man ein Farbtuch wählt, dessen Farbausnutzung pro laufenden Meter über die gesamte wirksame Farbtuchlänge mindestens 304( beträgt. Ein solches Farbtuch besteht beispielsweise aus einem Nylongewebe mit 112 Fäden pro ce2 und 34 Binzelfasern pro Faden.The economy can be increased by using a colored cloth selects its color utilization per running meter over the entire effective color sheet length is at least 304 (. Such a colored cloth consists, for example, of a nylon fabric with 112 threads per ce2 and 34 single fibers per thread.

Bei einem Farbtuch der zuletzt genannten Art ist die aufnehmbare Farbmenge besonders hoch. Das gleiche gilt für die Farbabgabe. Wie sich gezeigt hat, wird die gegenüber bekannten Farbtüchern erhöhte Farbaufnahme im Betrieb voll wieder abgegeben. Dadurch kann die absolute Farbabgabe in Gramm bei einer Steigerung der Farbaufnahme von etwa 20% praktisch verdoppelt werden.In the case of a color cloth of the last-mentioned type, the amount of color that can be absorbed is especially high. The same goes for the color release. As it turned out, will the increased color absorption in operation compared to known color cloths fully again submitted. This allows the absolute color release in grams with an increase in Color absorption of around 20% can be practically doubled.

Das erfindungsgemässe Farbtuch bietet auch ökologische Vorteile, da die verbesserte Farbausnutzung den Abfallanteil an Farbtüchern spürbar reduziert.The color cloth according to the invention also offers ecological advantages because the improved color utilization noticeably reduces the amount of waste on color cloths.

In den nachstehenden Tabellen sind die Ergebnisse von Versuchen an einem bekannten 18 m langen Farbtuch aus einem Nylongewebe mit 108 Fäden/cm2 und 13 Einzelfasern pro Faden (Tabelle 1) und an einem erfindungsgemässen 9 m langen Farbtuch aus einem Nylongewebe mit 112 Fäden pro cm2 und 34 Einzelfasern pro Faden (Tabelle 2) dargestellt. Ein Vergleich der Tabellen zeigt die deutliche Überlegenheit des erfindungsgemlssen Farbtuches.In the tables below are the results of experiments a well-known 18 m long colored cloth made of a nylon fabric with 108 threads / cm2 and 13 individual fibers per thread (Table 1) and on a 9 m long according to the invention Color cloth made from a nylon fabric with 112 threads per cm2 and 34 individual fibers per thread (Table 2). A comparison of the tables shows the clear superiority of the color cloth according to the invention.
