Definitions

  • This invention is concerned with an apparatus for manufacture of a point applicator.
  • a principal objective of this invention is to provide a flocked paint applicator in which the fibers have a generally uniform orientation with respect to the base, preferably extending from the base at an angle rather than normal thereto, overcoming the difficulties described above.
  • a paint roller sleeve comprising a cylindrical base having fibers secured to the outer surface thereof, each fiber extendving outwardly from the base and generally at an acute angle with respect to a plane tangent to the base and the orientation of the fibers with respect to the associated plane being substantially the same.
  • the fibers lie in generally radial planes, at right angles to the longitudinal axis of the hase and each forms an acute angle with respect to the related tangent plane.
  • the fibers lie in planes extending longitudinally of the base and passing through the longitudinal axis.
  • Yet a further feature of the invention is the provision of an apparatus for depositing fibers on a sleeve in which the fibers are dropped from a source past a sleeve supporting spindle with means establishing an electrostatic field between the spindle and electrodes adjacent thereto.
  • FIG. 1 is an end view of a paint roller sleeve embodying the invention
  • FIG. 2 is a diagrammatic elevation of an apparatus for manufacturing the sleeve of FIG. 1;
  • FIG. 3 is a view taken from the left of FIG. 2;
  • FIG. 4 is a longitudinal section through a modified sleeve
  • FIG. 5 is a diagrammatic illustration of an apparatus for manufacturing the sleeve of FIG. 4;
  • FIG. 6 is a diagrammatic view of another apparatus formanufacturing applicators embodying the invention.
  • FIG. 7 is a perspective view of another paint applicator embodying the invention.
  • FIG. 8 is an edge view thereof.
  • the apparatus herein produces a flocked paint applicator which does not have the erratic painting characteristics of other flocked applicators. It: is our theory that the application of the flock material in a manner in which the fibers have substantially the same orientation with respect to the base eliminates the tendency of the applicator to move laterally during use.
  • a paint roller sleeve 10 has a cylindrical base 11 which may be formed of a spiral wrapped multi-ply paper impregnated with a waterproofing substance.
  • a layer 12 of adhesive covers the outer surface of the sleeve.
  • Flock fibers 13 have their ends embedded in the adhesive 12 and extend outwardly from the sleeve surface.
  • the fibers 13 each lie in a generally radial plane at right angles to the longitudinal axis of the tubular base 11 and form an angle of the order of 15 with respect to an extension of the radius, Or an angle of with respect to a plane tangent to the surface of the base. Substantially all of the fibers are oriented so that they extend generally in the same relative direction with respect to the surface of the base.
  • the fiber material, diameter and length are determined primarily by the specific use for which the roller sleeve is intended.
  • a fiber suitable for enamels may not be satisfactory for a water base paint, for example.
  • the fibers are of a synthetic plastic material, as nylon.
  • FIG. 2 An apparatus for depositing fibers on the base in the manner shown in FIG. 1 is illustrated in FIG. 2.
  • the cylindrical base 11 has its outer surface coated with a suitable adhesive and is mounted on a rotating conductive spindle 15 located between conductive electrode panels 16 and 17.
  • a flock sifter 1 8 is located above the spindle and has a screenlike or foraminous bottom 19 through which flock fibers 13 are discharged, to fall under the influence of gravity between the spindle and the electrode.
  • a reciprocating blade 20 agitates the fibers in the sifter and insures a continual and relatively uniform flow to the flocking enclosure.
  • a power supply 21 has one terminal connected with conductive spindle 15 and the other connected with ground 22 and thus to grounded electrodes 16 and 17.
  • the fibers drop from the grounded sifter 18, acquire a charge and are attracted to the charged spindle inside base 11. Some of the fibers are charged as they leave the sifter while others fall against electrode 17, acquire a charge and are then attracted to the spindle. This attraction causes the ends of the fibers to be embedded in the layer of adhesive on the outer surface of the sleeve with the fibers extending outwardly therefrom. To insure that all the particles are oriented in the same direction, the movement of the particles is directed peripherally around the spindle and base in only one direction. In the apparatus of FIG. 2, this is achieved by providing a baflle element 23 which is a portion of grounded conductive electrode 16.
  • the baffle extends above at least one-half of the spindle and roller sleeve base 11 and along the length of the base.
  • Bafile 23 prevents flock fibers from traveling counterclockwise about base 11 and being attracted to the base with an orientation different from those which pass clockwise about the same. Rotation of the spindle exposes all portions of the base to the flow of fibers and insures uniform coating with the fibers.
  • the air within the flocking enclosures is preferably maintained in a quiescent condition so that the pattern of the falling fibers is not disturbed.
  • Flock fibers which are not deposited on the sleeve as they pass downwardly between the spindle and electrodes are received in a pan 24 below the electrodes.
  • Flock particles may be returned from the pan 24 to sifter 18 if desired.
  • a blower (not shown) may continuously recirculate the particles.
  • the adhesive is cured in a suitable manner, as by placing the sleeve in an oven.
  • a specific mechanism for rotating spindle 15 is not illustrated herein. Any suitable mechanism may be used. Such, for example, as that shown in the Thackra et al. patent where the spindle is moved on a continuous chain conveyor and carries a spur gear at one end which engages a fixed conveyer and carries a spur gear at one end which engages a fixed rack to effect rotation.
  • FIGS. 4 and 5 another form of roller sleeve 30 embodying the invention is illustrated.
  • the fibers 31 lie in planes which extend longitudinally of the cylindrical base 32 and pass through the longitudinal axis of the base.
  • the fibers 31 are oriented in the same direction as can be seen in FIG. 4, and have an angle of the order of 150 to with respect to a radial plane or of 75 to 70 with respect to a plane tangent to the surface of the base.
  • the uniform orientation of the fibers eliminates erratio operation and assures a smooth, even application of paint.
  • the apparatus illustrated in FIG. 5 applies the flock fibers in a manner which produces the roller sleeve of FIG. 4.
  • Cylindrical sleeve base member 32 is mounted on a conductive spindle 35 which extends vertically between grounded conductive electrodes 36 and 37.
  • the flock fibers are discharged through the bottom of the sifter 38 as blade moves back and forth.
  • the conductive spindle 35 is connected with a terminal of power supply 42, the other terminal of which is grounded.
  • the electrostatic field set up between the spindle and electrodes 36 and 37 attracts the fibers and their ends are embedded in the adhesive covering of the sleeve base.
  • the fibers hang downwardly from a horizontal plane imparting the uniformly oriented angular relationship illustrated in FIG. 4. Again, the majority of the fibers are not randomly app ied to the base, but are oriented uniformly.
  • the flock fibers have no component of movement peripherally of the sleeve base 32, but travel longitudinally with respect thereto.
  • the concept of unidirectional peripheral movement discussed above and incorporated in the claims is defined as including axial or longitudinal movement where the peripheral component is zero.
  • the fibers which pass by the sleeve are collected in grounded pan 43 and may be returned to sifter 38 in a suitable manner.
  • FIG. 6 illustrates another apparatus embodying the in vention.
  • Spindle 50 is positioned in a generally horizontal plane between grounded electrodes 51 and 52.
  • the spindle is connected with a suitable power supply 53 establishing an electrostatic field between the spindle and the electrodes.
  • the flock fibers 54 are deposited from a hopper 55 on a conveyor belt 56 which travels beneath the spindle 50. As the particles pass beneath the spindle, they are drawn upwardly by the electrostatic field and deposited on the adhesive coated surface of roller sleeve base 57 which is mounted on the spindle.
  • An agitator bar 58 located beneath the conveyor belt 56 may be rotated to disturb the fibers subjected to the influence of the field which then draws them upwardly to be deposited.
  • a portion 59 of electrode 51 extends beneath spindle 50 and serves as a bafile to direct the fibers to the right hand side of the spindle so they have a unidirectional component of motion with respect to the sleeve base. As in FIG. 2, the spindle is rotated to insure uniform distribution of the fibers.
  • FIGS. 7 and 8 illustrate another form of the invention in which the applicator is fiat rather than cylindrical.
  • a flat applicator may be useful in applying paint in corners or to small surfaces which cannot readily be coated with a roller.
  • the applicator has a flat planar base to which are secured fibers 66, as by an adhesive layer 67.
  • the fibers 66 are deposited on the base at an acute angle (of the order of with respect to the surface of the base, for example).
  • substantially all the fibers have the same orientation with respect to the base so the applicator will move smoothly across the surface to be coated.
  • Apparatus for depositing fibers on the outer surface of a cylindrical base to form a paint roller sleeve comprising:
  • means including an electrode, supporting said base in a quiescent atmosphere
  • electrode means spaced from said base supporting means and connected with said high voltage source to establish an electrostatic field extending radially of said base across a [fiber application zone; and means for directing fibers from said source to said fiber application zone for deposition on said base, the peripheral component of movement of the fibers with respect to the cylindrical base being unidirectional.
  • said base supporting means includes a horizontally extending rotating spindle
  • the electrode means includes a conductive member spaced radially from and on one side of said spindle
  • said means for directing fibers includes a baffie extending the length of said spindle and located between said source and the other side of the spindle.
  • the apparatus of claimS including a grounded baflle extending axially the length of said base and covering substantially one-half the upper surface of said base.
  • Apparatus for depositing fibers on the outer surface of a cylindrical base to form a paint roller sleeve comprising: a flock sifter having a discharge port in the bottom thereof; a conductive rotating spindle extending horizontally below said sitter; electrodes of conductive material adjacent said spindle, including a baflie portion extending the length of and above one'half of said spindle; and a source of high potential connected between said References Cited UNITED STATES PATENTS 2,047,525 7/ 1936 Thode 117-17 2,358,227 9/1944 Hiers 118-636 X'R 2,497,696 2/1950 Smith 117-17 XR 2,789,075 4/1957 Stahl 29-120 X R 2,806,803 9/1957 Thackara et a1.
