Definitions

  • This invention relates to a method and apparatus for forming words of printed characters on strips of tape.
  • a dry transfer sheet comprises a light-transmitting carrier sheet on which a font of letters is printed (e.g. by screen printing).
  • the carrier sheet has high release qualities and the printed surface is coated with a low-tack adhesive.
  • the adhesive surface is placed on a receiving surface and its position adjusted until a selected letter overlies a desired area of the receiving surface.
  • the back of the sheet at the selected letter is then burnished with a stylus or the like.
  • the burnishing action functions to release the letter from the carrier sheet and simultaneously activate the low-tack adhesive, causing the letter to adhere to the receiving surface.
  • the letter is printed in reverse on the carrier sheet and, therefore, is viewed directly on the receiving surface.
  • Formal training is not required to achieve excellent results using dry transfer lettering sheets. However, some degree of judgement is necessary to ensure proper spacing and base-line alignment of the letters.
  • Kroy Industries, Inc. has introduced a lettering machine which enables the user to form a word on the non-adhesive surface of a transparent adhesive tape which can then be adhered in its entirety to a receiving surface, for example, an advertising layout, blueprint, or the like. (A machine of this general type is shown in U.S. Patent Specification No. 3,834,507.) The baseline alignment and spacing between letters is controlled automatically.
  • the Kroy machine is relatively expensive and somewhat cumbersome (about the size of a small typewriter)but is very easy to use, requiring virtually no skill. However, although automatic base-line alignment is desirable,better results are generally obtained if the user has some control over letter spacing. Moreover, the machine provides only a relatively limited number of typefaces and type sizes, and the definition of the typed letters is inferior to that of dry transfer lettering. In addition, because the Kroy machine involves a carbon paper type transfer which appears on the exposed (upper) surface of the tape, the images tend to smudge when the tapes are handled.
  • French Patent Specification No.1,214,051 discloses a transfer system including a transparent or translucent adhesive coated receptor sheet which can be used to pick letters sequentially from a release-surfaced sheet on which those letters are printed. The system there described, however, is cumbersome and has never been commercialised. No apparatus for use with such a system is disclosed in Specification No. 1,214,051. British Patent Specification No. 906,935 discloses such apparatus, but it is cumbersome to use and has never been commercially available.
  • the problem underlying the invention is to provide a device for use in forming words or other legends on tape which is inexpensive and easy to operate, and wherein the definition of the individual letters is comparable to that of a printed image.
  • a further object of the invention is to provide a device which overcomes or at least lessens the above-mentioned drawbacks of the Kroy machine and the apparatus of Specification No. 906,935 and which is no more difficult or time-consuming to operate, and which can be used easily and quickly to form transferred legends on labels which can then be applied where desired.
  • a novel tape dispensing device is used in conjunction with a . character sheet containing letters or other characters printed on a carrier sheet having high release characteristics.
  • the dispenser contains a roll of a pellucid adhesive tape (e.g. "Scotch” brand tape) which can be dispensed e.g. through an opening in the dispenser, and brought to lie on a frame extending from the dispenser adjacent the opening.
  • the frame includes an elongated window, the width of which is less than the width of the tape.
  • a strip of tape is pulled from the dispenser and adhered to the frame overlying the window. The user then places a selected area of the strip of tape overlying the window above a selected character on the carrier sheet and applies pressure to the back of the tape.
  • the method of the invention is used to form the labels with words, the letters being sequentially transferred from sheets of printed letters.
  • the process is not limited to lettering, and as used herein, the term ".character” is intended to include any type of indicia such as letters, numerals or symbols.
  • word as used herein thus means any assemblage of characters.
  • the tape dispenser may be part of an apparatus which provides base-line alignment of the transferred letters.
  • a base is provided on which the character sheet is secured.
  • a slide is mounted on the base for horizontal movement relative to the sheet and the tape dispenser is mounted on the slide so that the tape dispenser can move vertically.
  • any portion of the tape overlying the window can be positioned over any selected letter to effect transfer of that letter.
  • the letters are printed on the indicia sheet in rows with a preselected distance between adjacent rows, and the tape dispenser and slide include cooperating indexing means so that the window is indexed to the same base-line position relative to each of the rows.
  • Figures 1 to 6 show features of apparatus constituting a preferred embodiment of the invention.
  • the apparatus includes a rectangular base 10 having parallel elongated tracks 14 in its two long sides.
  • a slide 18 formed as shown in Figure 3 bridges the base 10 and slideshorizontally (for example) within tracks 14.
  • a character sheet 20 is accurately aligned on the top surface of base 10 by means of alignment pins 22 which pass through precisely located alignment holes (not numbered) within the sheet 20.
  • the character sheet 20 in the illustrated embodiment includes rows of letters of a selected size and typeface.
  • the character sheet 20 comprises a carrier sheet 26 (not necessarily light-transmitting) having at least one surface of high release properties on which letters 28 are printed.
  • the opposite (rear) surface of the carrier sheet 26 may be coated with an adhesive 30 so that the sheet will adhere tightly to the upper surface of the base 10 for reasons which will become apparent.
  • the base may be coated with an adhesive, or mechanical means may be used to hold the character sheet against the base 10 so that the individual letters ' may be pulled from character sheet 20 as explained below.
  • the carrier sheet 26 may be polyethylene
  • the characters 28 may be screen printed using a nitrocellulose based ink
  • the adhesive 30 may be an acrylic adhesive coated (e.g. by screen printing an area of adhesive) on the back of the polyethylene carrier.
  • a tape dispenser 32 contains a roll of pellucid, adhesive tape 34.
  • Tape 34 preferably comprises a transparent plastic backing 35 coated with an agressively tacky adhesive 37 ( Figure 2A). Numerous types of commercially available transparent or translucent adhesive tape may be used as tape 34.
  • the roll of tape 34 is rotatably mounted within dispenser 32 in conventional fashion.
  • the tape (viewed in Figure 2) rotates in a clockwise direction so that the tape may be pulled through an opening 36 at the base of dispenser 32.
  • an elongated rectangular frame 40 extends from the dispenser 32 adjacent the opening 36.
  • the frame 40 includes a similarly shaped window 42, the short dimension of which is less than the width of the tape 34 so that the edges of the tape can be adhered to the upper surface of the frame defining the window 42.
  • a cutting edge 46 is provided at the end of frame 40 opposite opening 36 to sever strips of tape from the roll 34.
  • the frame 40 is channel. shaped in cross section with two short downwardly depending rims 50 supporting the surface which defines window 42 slightly above the printed character sheet 20.
  • the distance between the rims 50 is such that the frame straddles a row of letters on character sheet 20 when the frame 40 is aligned for transfer.
  • the slide 18 includes a central generally rectangular opening 60 having a series of detents 62 along one edge. These detents are spaced apart a distance equal to the distance X ( Figure 1), which is the distance between the base-lines of adjacent rows of printed letters on the character sheet 20.
  • the tape dispenser 32 and the attached frame 40 are mounted on a dispenser carriage which comprises an upper generally U-shaped bracket 64 and a stepped block 66 secured together by screws 68.
  • the stepped block 66 includes an upper portion 70 and a lower portion 72 so that when the bracket 64 and block 66 are secured together, the upper portion 70 slides within the opening 60, with the lower portion 72 and the carriage 64 preventing removal of the carriage from the opening.
  • An indexing mechanism includes two steel balls 76 and coil springs 78 in channels (not numbered) within the upper portion 70 of block 66.
  • the balls 76 can be biased by springs 78 into pairs of detents 62 to enable the user to position the carriage (and thus the tape dispenser mechanism) in exact alignment with any of the printed rows of letters on the indicia sheet 20.
  • Figure 4 illustrates the manner in which the steel balls 76 nest within detents 62 to index carriage 64 so that the window 42 will be positioned in the same relative position with the letters of each row. This provides automatic base-line alignment of the letters transferred to the tape.
  • the bracket 64 is shaped to form a channel that can receive a complementary T-shaped mounting block 80 secured to the bottom of the tape dispenser 32.
  • the apparatus is used by pulling a length of the tape from dispenser 32 across the frame 40 and applying light pressure to the tape causing it to adhere to the top surface of frame 40 with a substantial part of the tape overlying the window 42.
  • the tape dispenser is then moved vertically and horizontally until a selected letter appears in the window at the desired location.
  • Pressure is then applied to the rear surface of the tape strip 34 directly above the selected letter. This may be done as shown in Figure 6 by means of a blunt instrument 90 having a rubber tip 92 which will cause only the area of the tape strip adjacent the selected letter to contact only the selected letter.
  • a beneficial feature of the invention resides in the flexibility of the frame 40.
  • the upper edges of the frame 40 tend to flex downwardly, enabling the tape to contact the selected letter 28.
  • the elasticity of the frame causes the tape to lift off of the surface of the indicia sheet 20.
  • the tape includes relatively tacky adhesive and since the carrier sheet 26 has high release properties, the effect is to transfer the letter or other character 28 from the carrier sheet 26 to the adhesive tape 34.
  • the entire word is composed by transferring successive letters, with the tape dispenser being moved appropriately to select and transfer the desired letters with proper spacing therebetween. Because of the detent mechanism, the base-lines of the letters will be automatically aligned; however, the user can adjust the spacing between adjacent letters by moving the slide 18.
  • the tape is lifted from the frame 40 and pulled from the dispenser.
  • the tape strip bearing the formed word can then be severed from the tape roll by means of the knife edge 46 leaving a second blank strip of tape in position over the window 42.
  • the severed tape strip containing the desired word may then be adhered to any desired receiving surface using the tacky adhesive. Since the letters are on the same side of the tape as the adhesive, the clear backing serves as a protective film after the tape has been adhered to a receiving surface.
  • character sheets containing characters of different sizes will be used.
  • interchangeable dispensers (and frames) of different widths it may be desirable to have interchangeable dispensers (and frames) of different widths.
