Abstract

A moulded filling material for packaging purposes is made by mixing cellulose pulp, fibre residues, cellulose power, waste paper and dust with swelling agents, starch prods. and additives to give a mixt. of the required consistency, and extruding the mixt. using an extruder with a thermal and mechanical action with a redn. in temp. and press. upon extrusion to cause expansion of the extruded prod. Pref. the components are mixed to give an extrusion mixt. contg. ca. 60% cellulose and a remainder of starch prods., swelling agent and regulating additives. A cutter is provided to cut the extrudate into packing pieces of the required size.

Description

Gegenstand der Erfindung ist ein Verfahren zum Herstellen von Füllmaterial für Verpackungszwecke aus Zellstoff - Faserresten - Staub - Mull. Dem Ausgangsmaterial werden Quellkörper in unter­ schiedlicher Menge je erforderlicher Konsistenz beigegeben. Zudem werden Stärkeprodukte und Zutaten beigemischt. Die nach weiterer Verarbeitung entstehende Masse wird beim Durchlauf in einem mechanisch und thermisch einwirkenden Extruder verdichtet und plastifiziert. Beim Extruderaustritt wird die Masse durch Temperatur und Druckabfall aufgeschäumt. Am Ausgang des Extruders ist ein Trenn­ mechanismus angebracht, der den austretenden Massestrang schneidet und den Füllkörpern die richtige Größe gibt.The invention relates to a method for producing Filling material for packaging made of cellulose - fiber residues - Dust - gauze. The source material becomes swelling bodies in under different amounts added depending on the required consistency. In addition starch products and ingredients are added. The one after another The resulting mass is processed in one pass mechanically and thermally acting extruder compresses and plasticized. At the extruder outlet, the mass is determined by temperature and foamed pressure drop. There is a separator at the exit of the extruder mechanism attached that cuts the emerging mass strand and gives the fillers the right size.
