  • the band may alternatively frictionally engage the side walls of the spool, either by squeezing pressure applied by the user, or by the clamping force exerted by the latching means described above. In its normal state the band may rest inside radially the walls of the spool which act to prevent the band sliding off the spool laterally.
  • the maximum diameter of ribbon on the spool may be less than the minimum diameter of the band to avoid variations in drag force on the ribbon as the ribbon diameter reduces in use.
  • the band 13 may be located in opposite slots 24 in the spool rims 25 as illustrates in Fig. 7, and the necessary drag force imposed by choosing appropriate slot dimensions.
  • the drag force may be exerted or increased by axial pressure applied to the opposite sides 25 of the spool.

  • the end portions may be guided in opposite slots of the spool flange.
  • Fig. 8 shows a spool 11 having an arcuate track 41 on the internal face of one flange 42 - a similar track is provided on the facing flange.
  • the ribbon supply is illustrated by reference 43 and the ribbon exit path by reference 44.

  • the arcuate track 41 may be circular.
  • Fig. 9 illustrates an alternative embodiment in which the upstanding end portions 14a,15a, are formed at the end of radially extending pairs of arms 31,32.
  • the inner ends of arms 31 and 32 carry extensions 33 which extend towards one another and are dimensioned to fit the centre aperture of a ribbon spool.
  • This embodiment is intended to be of flexible plastic and capable of being snapped over opposed rims of a spool as illustrated in Fig. 10.
  • the arms 31,32 are sufficiently resilient to permit the end portions 14a,15a to be squeezed towards each other to effect ribbon curling. Drag force may be exerted by the axially inwards gripping force of the arms, or by a radial force exerted between the inner extensions 33 and the undersides of the end portions 14a, 14b.
  • This embodiment may also include the features of opposed abutments to define a constant ribbon approach angle, and ribbon shredding teeth.
  • Uncurled ribbon may be drawn off by avoiding the curling blade on end portion 14a.

  • the device 110 comprises an arcuate base 111 having an upstanding leg 112 at one side, and a transverse arm 113 perpendicular to the leg 112 and generally overlying the base 111 as illustrated.

  • the thumb pad 114 and base 111 may in use be squeezed together, and in that case the device is advantageously manufactured as a one piece plastics moulding.
  • the device In use the device is placed over a reel 116 of ribbon 117 as illustrated in Figs. 13 and 14; the dimensions of the device are determined by the reel dimensions, and the device may include one or more integral catches to loosely grip a flange of the spool. Such a catch may comprise a projection on the underside of arm 113, spaced from but facing towards upstanding leg 112.

  • Fig. 17 may be especially useful with ribbon having only one side suitable for curling, for example a ribbon with a metallic finish on one side only.
  • Such ribbons are for presentation reasons always wound with the decorative side to the outside, and it is consequently necessary to curl the inner face as provided for in the Fig. 17 embodiment.
  • the device can include a protective shield for the blade which may extend arcuately over the blade edge; the shield may be moulded integrally with the device.
  • the curling edge may be omitted so that device comprises splitting hooks only.
  • this invention is intended to encompass a spool within spool construction in which a loose spool of ribbon revolves freely within an outer spool shaped casing of which the device is part.

Abstract

Un distributeur servant à distribuer des noix ou d'autres matières particulaires ou granulaires comprend une enveloppe en plastique creuse et transparente, généralement rectangulaire, pourvue de parois avant et arrière (10, 12), ainsi que de parois latérales (14, 16). En cours d'utilisation, un récipient pour noix, scellé sous vide, est placé dans l'extrémité supérieure de l'enveloppe. Un corps généralement cylindrique (32) est monté entre les parois avant et arrière (10, 12), sur un axe (38) pouvant être mis en rotation par l'intermédiaire d'une poignée (46). Deux volets à déformation élastique (48, 50) font saillie de façon à entrer en contact avec la surface cylindrique du corps (32). Un matériau provenant du récipient (18) est amené par la force de la gravité à descendre vers le corps (32) et dans l'un des deux évidements (34, 36) pratiqués sur la surface externe de ce dernier. La rotation du corps (32) au moyen de la poignée (46) limite le niveau de matériau dans l'évidement (34, 36) mais l'élasticité des volets (48, 50) empêche le blocage de l'installation si de grosses particules (telles que de grosses noix) doivent être distribuées. Grâce à une rotation additionnelle du corps (32), le matériau nivelé est déchargé par gravité par l'extrémité inférieure du distributeur.
