  • the tape bending tabs 528 which protrude toward each other from the respective tape roll guides 508 beneath the tape cutting edge 517 may "catch" or engage and pull back the portion of the tape segment 533 which remains attached to the tape roll 530.
  • the pulled-back tape segment 533 assists the user in finding, grasping and subsequently pulling and cutting the next tape segment 533 from the tape roll 530.
  • the next tape segment 533 can be removed from the tape roll 530 in the similar manner, by positioning the tape cutting device 501 on the tape roll 530 behind and within the distance to the extending tape segment 533 which corresponds to the desired length of the tape segment 533 and then grasping and pulling the tape segment 533 against the tape cutting edge 517 of the tape cutting blade 514 to form the severed tape segment 535 (FIG. 36C), as was heretofore described.
  • the tape cutting device 501 As the tape segments 533 are cut and dispensed from the tape roll 530, the tape cutting device 501 is pushed or "rides” along the tape roll 530 to position the tape cutting edge 517 of the tape cutting blade 514 at the selected positions along the tape 532 for cutting and dispensing of the tape segments 533 of selected length.
  • the elastic retainer cord 521 of the retainer mechanism 520 is constantly in a contracted state and thus, continually maintains a secure and snug fit of the tape cutting unit 507 against the tape roll 530.
  • the retainer cord 521 contracts and continues to snugly secure the tape cutting unit 507 on the tape roll 530 and prevents loosening of the tape cutting unit 507.
  • the retainer mechanism 520 can be selectively tightened, as necessary, by pulling the retainer cord 521 upwardly in the cord slit 525 in the tape cutting unit 507.
  • the tape cutting unit 507 can be removed from the spool 531 by disengaging the retainer member 522 from the retainer seat 524 in the device panel 502 and removing the retainer cord 521 from one or both of the cord slits 525.
  • the tape cutting device 501 can be subsequently used in a similar manner on a fresh tape roll 530.

Abstract

La présente invention concerne un dispositif de coupe de bande comprenant une unité de coupe de bande conçue pour se déplacer le long d'un rouleau de bande. L'unité de coupe de bande comprend un panneau de dispositif. Deux guides de rouleau de bande espacés l'un de l'autre s'étendent depuis le panneau de dispositif. Une lame de coupe de bande présentant un bord de coupe de bande s'étend entre les guides de rouleau de bande. Deux pattes de pliage de bande s'étendent à partir des guides de rouleau de bande respectivement, l'une vers l'autre et dans une relation espacée l'une de l'autre vers le bord de coupe de bande de la lame de coupe de bande. Un mécanisme de retenue est porté par l'unité de coupe de bande. Le mécanisme de retenue est conçu pour fixer l'unité de coupe de bande sur le rouleau de bande.
