To all whom it may concern Be it known that I, Dr. OTTO EBERHARD, a subject of the German Emperor, residing at 7 Bergstrasse,Heidenau,near Dresden, in the German Empire, have invented certain new and useful Improvements in Methods of Drying Objects Formed of Plastic Masses, of which the following is a specification.
The drying of objects formed from plastic masses, particularly those containing a large proportion of water, is attended with difliculty because if the drying is not uniform strains may readily arise in the material and produce undesirable modifications of form.
It has been found that a uniform drying only takes place if during the entire course of the drying all the parts of the object to be dried come perfectly uniformly into contact with the source of heat or with the hot air by means of which the drying is effected.
None of the drying processes hitherto adopted fulfils this condition completely. In employing vacuum apparatus with hot plates radiation of heat in various directions differs, even when the material is rested or suspended exactly centrally be tween two plates. In what are called grid driers the air can never be supplied so uniformly that a completely uniform drying takes place, in particular the lower side of the material or object to be dried does not come into contact with the hot air in the same manner as the upper side, the same applies to the ordinary drying apparatus provided with continuously moving bands.
By means of the novel method of drying all these defects and difficulties are eliminated owing to the fact that during the drying operation the material under treatment, no
matter whether in vacuum apparatus, dry-- ing cupboards or the like is given a uniform displacement which produces a constant.

mell one among the. other sothat such driers are not suited for drying rods formed from P1381310 masses, ln-accordance with the punciple of the present invention, which, as stated above, presupposes a regulated modification in the position of the surface of the objects treated.
My U. S. Patent 1,088,555 of February 24,
1914, relates to apparatus for drying articles formed from plastic masses. while my first invention has'for its object the process upon which said apparatus is made.
The novel process can be carried into practice in a simple manner by an arrange? ment accordingto the drawings. In this case the rotary movement can be produced by displacing an endlesscloth on which rollable rods to be dried are placed, supports or stops being arranged over thiscloth at various places for preventing the. material from participating in the advancing movement of the cloth.. In this manner the material is The drying itself can also be effected by means of hot air or in cacao.
Numerous embodiments of the invention are illustrated by way of example in the accompanying drawing.
Figure 1 shows a drier suitable for drying round rods with rotating belt in side elevation. Fig. 2 is a corresponding front elevation.
In Figs. 1 and 2 endless rotating belts p .are provided and over these beltsstationary supports 9 extend. The round rods 0 are placed upon the belts p between the supports q and owing to the friction on the belts moving beneath the supports 9 experience a uniform. rotation.
. What I claim and desire to secure by Letters Patent of the United States is 1. The herein described method for dryterial, consisting in imparting to the articles to be dried simultaneously a uniform constant rolling movement relatively to their base by supportingthem on their entire length and limiting the position of said articles, so as to produce a constant uniform influence of the drying medium upon the whole surfaceof the rolling articles.
