Definitions

  • This invention relates to card clothing for covering the cylinders or rollers of textile carding engines and similar machines.
  • Orthodox card clothing usually consists of a suitable foundation material set with wire teeth whose crowns or heels are arranged paraxially to the cylinders or rollers upon which the clothing is secured.
  • the teeth of the clothing tend to become choked with fibre and foreign matter, consequently, periodic cleaning or fettling of the card teeth has to be effected during stoppages of the machines, resulting in considerable loss of working time and variations in quality of the carded material.
  • the fettling operation is a somewhat tedious and unpleasant task.
  • An object of the present invention is to reduce the time lost for cleaning and maintaining card clothing by providing new or improved card clothing for textile carding engines and similar machines whereby the teeth of one roller or the like automatically clean the teeth of a coacting roller during operation of the machines.
  • This cleaning action may operate either simultaneously with usual carding operations of the teeth or may function solely for cleaning purposes.
  • the new or improved card clothing consists of a foundation material in which are set wire teeth, said teeth each having two limbs which are joined at their bases by a crown or heel and which lie in the same plane as said heel, said teeth being set in said material in a manner whereby the heels of the said teeth occupy or lie in a direction corresponding approximately to the direction of rotation of the rollers or the like to which the clothing is secured, that is to say, with one limb of each tooth leading to the other limb.
  • Such a disposition of the teeth imparts stability thereto as compared with the orthodox disposition because the rearward pressure on the teeth during operation of the machine is resisted by the resilient strength of the tooth acting along its longitudinal axis in which its limbs and heel lie, whereas with the orthodox disposition the teeth offer little resistance.
  • the working limbs that is the limbs of the teeth which operate with the cleaning action, are inclined, with respect to the foundation material, rearwardly relative to the direction of rotation of the roller on which they are mounted so as to clean with a dragging motion as opposed to a digging or prodding motion.
  • each tooth may be in a simple substantially U form with the two limbs of the tooth of the same or unequal length, and lying in a plane at 90 to the foundation material.
  • This arrangement of teeth should not preclude any of the other arrangements of length of limb and angle of inclination to the foundation material which are hereinafter described, from being used on a dickey or doffer stripper roller or separate cleaning roller to be used in cleaning any rollers on a carding engine or similar machine.
  • the actual arrangement of tooth, length of limb and angle of inclination to foundation material is governed by the type of material (e.g. wool, cotton, silk, synthetic fibres or mixtures of any of these fibres) to be processed on a carding engine or similar machine.
  • Each tooth may have two upstanding limbs of the same or different lengths and one limb may be clenched down onto or into the foundation to. give increased stability.
  • the wire used for the teeth according to the invention is of somewhat higher tensile strength than that of normal card clothing wire.
  • FIG. 1 to 3 illustrate three diiferent forms of teeth according to the invention
  • Figures 4 and 5 are an elevation and perspective view respectivelyof another form of tooth
  • Figures 6 and 7 and 8 are respectively an elevation, plan and under view of a portion of card clothing according to this invention and shown as applied to a roller;
  • Figure 9 illustrates the use of the said clothing on the fancy roller of a carding engine
  • Figure 10 illustrates a substantially U form of tooth viewed in the plane in which it travels.
  • Figure 1 shows a form of tooth having a straight heel 1 and two limbs 2, 3 which are bent through an angle which is preferably between 55 and according to the type of material which is' to be processed by the carding or other machine with which the teeth are to be used.
  • the limb 2 is longer than the limb 3 and is the working limb which performs the cleaning action, its length being (say) from to 1%" according to the type of card clothing which it is to clean.
  • FIG. 6 to 8 This form of tooth is shown in Figures 6 to 8 set in a suitable foundation material m, each tooth being set with its heel lying in line with the direction of rotation of the roller on which it is mounted, this being indicated by the arrow in Figure 6.
  • the working limbs 2 thus have a rearward inclination in the same plane as the heel and the teeth may be set in any suitable pattern such as that illustrated where they are in rows having staggered sets of four, the rows being so spaced that the ends of the short limbs 3 lie amongst the limbs 2.
  • the form of tooth shown in Figure 2 has two limbs of equal length and equally inclined, the foremost limb 3a being also a working limb in this case.
  • This tooth is shown in Figure 3 viewed in the plane in which it travels, 3c representing either the front or the rear limb.
  • the short limb 3b is bent at to the heel 1 and is approximately half the length of the limb 2.
  • the end 3x of the limb 3 or 3b may be clenched down upon the face of the foundation in. either sideways as shown in Figures 4 and 5 or in any other desired direction.
  • one or both limbs of the teeth or the outer portions only thereof may be bent one or more times either in the plane of the heel, at right angles to such plane or in other desired directions. This may enable the teeth to be inserted in the foundation with the base of the limbs at any desired angle to the foundation, but ensure that their outer or working portions shall lie at the angle necessary to produce the cleaning or working effect according to the invention.
  • a method of employing the new or improved card Patented June 7, 1960 clothing for simultaneously effecting carding and automatic cleaning operations is to utilise the said clothing upon the fancy roller or rollers of a textile carding or similar engine.
  • This is illustrated in Figure 9"Which shows the normal card clothing teeth 4 on the swiftor orthodox clothing according to requirements.
  • a suitable clothed rolleror rollers may be'mounted upon the engine in proximity to the cylinder or rollers to be cleaned (for example, a swift or cylinder, a doifer, a stripper, a worker or a clearing roller) and suitable means ,provided for .driving the cleaning roller or rollers.
  • rollers whose card clothing has become laden with fibre to the extent that efficient working of the carding engine or similar machine is impaired may be cleaned.
  • the cleaning operation may be carried out continuously or intermittently so that any such rollers do not become laden with fibres to the extent that efficient working of the carding engine or similar machine is impaired, thus preventing loss of working time, reducing the variation in quality of product which takes place when the rollers are gradually becoming laden with material, and relieving operators of a somewhat unpleasant task.
  • Card clothing for covering the cylinders or rollers of textile carding engines and similar machines comprising in combination a foundation material and wire teeth, said teeth each having two limbs which are joined at their bases by a heel and which lie in the same plane as said heel, said -teeth'being' set in said material with their heels lying in a direction corresponding approximately to the direction of rotation of the cylinders or rollers around which the clothing is secured so that one limb of each tooth leads the other limb, each such tooth having at least its working limb inclined, with respect to the foundation material, rearwardly relative to the direction of rotation of the cylinder or roller around which said materialis to be secured.
  • Card clothing constructed as called for in claim 1, and wherein both limbs of each teeth are working limbs and are of the same length.
