0R CARDING FIBROUS Application filed November 1, 1928, Serial No. 316,603, and in Great Britain September 19, 1927.
This invention relates to metallic clothing for opening, breaking, preparing or carding fibrous substances. Heretofore this form of clothing has usually been made in the form of wire of a suitable cross section, with pieces cut out at proper intervals along it to leave a single row of teeth-of the required shape for the production of the desired effect. The wire so formed is then wound around grooved or plain surfaces of the cylinders or rollers to which it is to be applied to form multiple rows of teeth, its ends being secured by soldering, or in any other appropriate manner. The present invention has for its chief object to introduce an improved form of metallic card clothing which will be quite as efficient as the kind described, be as cheap, or cheaper to produce, be capable of being applied without the use of skilled labor and be equally applicable for covering curved or fiat surfaces.
According to this invention instead of the metallic clothing being constructed from wire with a single row of teeth, it is constructed from metallic strip or sheet of iron, steel or any other metal whatsoever, and numerous rows of teeth are obtained across the width of the ribbon or sheet by punching or stamping them out of the body of the material and bending them at right angles thereto, or to any other desired angle.
The teeth may be punched out or stamped in any desired order or form and may follow any of the known methods of setting as employed in connection with wire card clothing. To obtain closer setting, that is, more points per square inch, than can be obtained by punching, the body or foundation is corrugated or folded between the rows of teeth. The latter may be of any requiredform and may vary from the comparatively long and slender teeth used in metallic clothing for carding, to the sawtoothed form of various degrees of coarseness, or even to the flat toothed form as used for removing burrs or other foreign matter from certain fibres, or may be straight or curved or tapered from the base to point in either direction. The metallic strip or sheet may be of such character that it will enable the points or any other part of the teeth to be hardened, or tempered or ground either on the surface or down the sides, and it can be constructed of any desired thicknessand composition to suit different classes of work. When the metallic clothing is made in sheet or fillet or ring form, the ends, or sides, or both may be perforated at intervals or soldered or fitted with a prong, or be otherwise formed for attachment to the cylinders or rollers. The metallic clothing may be applied to any rollers or cylinders or flats or any other mechanism used in the opening, breaking, preparing, carding of textile fibres to which it is applicable and any such roller or cylinder or fiat or other mechanism may work in conjunction with another roller or cylinder similarly covered with a different type of card clothing, or with a card clothing having a different formation of tooth or with metallic wire. When the metallic clothim is made for application to flats it may be fbrmed with marginal edges, adapted to be secured to the flats by bending and clamping or it ma be formed with prongs to fit holes in the ats. If desired the bending operation may be effected before the metallic clothing is pressed on to the flat and be done in such manner that a slight amount of lateral tension will be imparted to the foundation as it is pressed into contact with the flat for keeping it flat against the surface of the latter when the marginal edges of the clothing are turned underneath the bottom edges of the flats. Flats so covered may work in conjunction with a cylinder covered with a similar ty e of metallic clothing, or with 35 clothing of any other appropriate form.
In the accompanying drawings, Fig. 1 is an elevation, Fig. 2 a plan, and Fig. 3 an end View of a form of metallic card clothing constructed in accordance with this invention.
A indicates the teeth, and B the metallic strip.
Referring to the example shown, the teeth A are punched out in rows arranged parallel with the edge of the strip B. This meth- 0d of setting the teeth leaves comparatively wide spaces between the teeth. To reduce the width of these spaces the strip is folded or corrugated between the rows of teeth as shown at b.
