T. GREIS CLOTH EXPANDING ROLLER Fi led Sept. 2. 1924 Patented Dec. 1, 1925 NETED STATES Lsfiflfitl PATENT OFFICE.
Tl-IECDOR GREIS, F CREFELD. GERMANY, ASS'IGNOR TO MASCHINENFABRIK BENNING'ER A. G1, UZATIL, SVITZERLAND.
CLOTH-EXPANDING ROLLER.
Application filed September 1 0 (all whom it may concern Be it known that I, Tnnonon Gnnrs, a citizen of the Republic of Germany, residing at Crefeld, Germany, have invented certain new andv useful Improvements in Cloth- Expanding Rollers, of which the following is a specification, reference being had. therein to the a :companying drawing.
Cloth expanding rollers provided on their circumference with screw thread which is right handed on one longitudinal half of the rollers and left-handed in the other longitudinal half are known. With these rollers the pitch of the thread is either constant or it increases from the middle of the roller towards its ends. The rollers provided with screw thread having an increasing pitch exert a better expanding action on the cloth moving over the rollers than rollers the screw thread of which has a constant pitch.
The object of the invention consists in providing a cloth expanding roller which can be manufactured much cheaper than the hitherto known rollers with which the thread is cut into the body of the roller. The initial costs of these known rollers are high as the screw thread must be very exactly finished so that the treated cloth is not impaired. The reduction in the initial costs is obtained by forming the thread by wire of a suitable cross-section which is Wound into grooves of any suitable profile cut into the roller, for instance on a lathe or on a planing machine, and with the aforementioned variable pitch.
A cloth expanding roller provided with a thread of this type presents further a considerable progress over the known cloth expanding rollers with which the helical windings are formed by a thread spirally wound on a smooth roller and soldered to the latter. The connection by soldering is no eflicient connection at any rate and the soldered places are moreover attacked by some of the liquids with which the cloth is soaked for instance in mercerizing. As only comparatively few materials are suitable for soldering the number of materials of which such rollers can be made is very limited.
constructional examples of the subject matter of the present invention are illustrated on the accompanying drawings; in which:
Fig. 1 is a diagrammatic View of a cloth 2, 1924. Serial No. 735,415.
expanding roller provided with left hand and right hand thread,
Figs. 2- l show parts of roller having grooves cut into their bodies and wire forming the thread lodged in the grooves,
Fig; 5 is an end view 01 a roller,
Fig. 6 shows partly in section and partly in view a cloth expanding roller provided with multiple thread which is formed by wires inserted in grooves.
The screw thread of the cloth expanding roller 1 diagrammatically illustrated in Fig. 1 has a pitch which increases from the middle of the roller indicated by a dash and dot line, towards the ends, the screw thread being left-handed in one longitudinal half and right-handed in the other longitudinal half of the roller.
Fig. 2 shows a part of a roller 1 into which a spiral groove 2 of a semi-circular profile is out with an increasing pitch and into which groove a wire 3 of circular crosssection is inserted. In Fig. 3 the grooves 2 are of a rectangular profile and a wire 8 of semi-circular cross-section is inserted in the grooves and in the embodiment shown in Fig. 4 the grooves 2 are of rectangular cross-section into which grooves a wire 3 of trapezoidal cross-section is inserted. A cloth expanding roller provided with thread according to Fig. elhas a particularly good gripping effect on the cloth.
Fig. 5 is an end view of the roller.
Fig. 6 shows an embodiment of the in vention in which the grooves 2 are out from the right to the left as single thread, double thread, triple thread and quadruple thread into the body 1 of the roller and wires 3 of trapezoidal cross-section are inserted in the grooves.
'lhe increase of the number of threads per pitch shows the advantage that the single threads are at approximately the same distance from each other although the pitch of the thread increases. The fabric is thus more evenly supported than is the case if there is only one winding per pitch.
The Wire is pressed into the grooves and is thereby held therein, the ends of the wire may be fixed, if deemed necessary, by any suitable means such as set screws, as is indicated in Fig. 5 at l.
The roller may consist of any kind of metal such as steel, cast-iron, bronze, copper and the like or of wood, ebonite and the like. The groove does not need to be deep and it may be produced in one cutting or planing operation. Further it does not need to be carefully machined as it is covered by the wire. Cloth expanding rollers, particularly rollers made of wood with a thread of metallic wire, manufactured in this manner are much cheaper than rollers into the body of which the thread is cut.
I claim:
1. A cloth expanding roller having screw threads on its circumference which is right handed on one longitudinal half of the roller and lefthanded on the other longitudinal half, the pitch of the thread increasing with an increased distance from the middle of the roller and the number of threads per pitch increasing with said increase in the distance and the thread being formed by a wire of suitable prolile and inserted in grooves cut into the body of the roller which grooves respond to the aforementioned conditions for the screw thread.
2. A cloth expanding roller having screw thread on its circumference which is right handed on one longitudinal half of the roller and left handed on the other longitudinal half, the pitch of the thread increasing with an increased distance from the middle of the roller and the number of threads per pitch increasing with said increase in the distance.
8. A cloth expanding roller comprising a cylindrical wooden body having spiral grooves cut into its circumference which are right handed on one longitudinal half of the roller and left handed on the other longitudinal hali, the pitch oi the grooves increasing with an increased distance from the middle of the roller, and the number oi windings per pitch increasing with said increase in the distance and wire inserted in said grooves the projecting part of which forms the screw thread of the roller.
In testimony whereof I affix my signature.
THEODOR UR E15.
