Description

April 26, 1955 c. NEUBRONNER 2,707,024 KNIFE MOUNTED on A HAND OPERATED CARRIAGE FOR DETACHING A STRIP OF MATERIAL FROM A ROLLER Filed Dec. 1, 1951 ;9 6a.. v 8 i, CARL'Nfl/BRON/VER /7a,
IN V EN T 0R. I W WW /7 ATTOR/Vfy United States Patent 17 Claims. (Cl. 164-42) OPERATED CAR- STRIP OF MATE- The present invention relates to a device strip is cut off, likewise by hand, by means of a knife arranged at this spot. The disadvantage of the known devices of this type consists in the fact that for pulling the a knife arranged at the end of the feed path.
he disadvantages of the known devices are overcome according to the invention by providing a single means for feeding the strip along a guide-track at the end he invention comprises will be more fully explained below.
Examples of the device according to the invention are illustrated in the accompanying drawing, in which:
longitudinal section through the device; Fig. 2 a front view of the same;
ig. 3 is a section taken along line A-B in Fig. 2; Fig. 4 an enlarged view of the part marked C-D in Fig. 1; and
Fig. 5 is a different embodiment of the knife.
up on both sides around the same. form lateral guide rails and passed over the bottom 5. Plate movement. A curved knife is mounted on carriage 9 rotatable on a 9, with the other end at 15 at the front of the inner casing wall. Instead of the tensioning spring arrangement, there may be spring arrangements of different kinds.
As shown more particularly in Fig. 4, guide track 4 terminates at the lower slot 16. In 17 which on one side is provided with a flap 17a extending over guide bars 8 (see also Fig. 3), and which on the other hed, under the action of springs 18,. against lower edge of guide track 4. At the lower end of device, a fiat guide member 19 is arranged for taking up the tape emerging from the side rails 6a, said member having the purpose of pressing the gummed strip against a brush 21 projecting from a water container 20.
device according to the invention operates as abutment ledge opening up between When, after severing the strip, pressure on bottom 15 is released by the operator lifting glide out operated individually for every function.
here may be many modifications of the device, illustrated by way of example. The knife support 12a, for instance, may be made as shown in Fig. 5. In this embodiment the support is pulled further down when rotated on pin 10 and an extended rear porlike. In this embodiby means of the extension 22, as
of limitation,
tions of the the spirit of my invention.
at I claim is:
action.

8. A device according to claim 6, wherein said knife support is provided with a knurled cover.
9. A device according to claim 6, wherein said knife support is provided with a knurled cover of rubber.
10. A device according to claim 6, wherein said knife support is provided with a knurled cover of plastic.
11. A device according to claim 6, wherein said knife support is provided with an extended rear portion capable of resting on said guide track, and a rubber cover for said extended portion.
12. A device for detaching a strip of gummed tape from a reel, which comprises a guide track for said strip, a hand-operated carriage adapted to slide upon said track, a knife mounted for rotation on said carriage, said knife being adapted for feeding said strip from said reel over said track, said track having an end face adjacent to a transversal slot, said end face and slot being adapted to cooperate with said knife in severing the strip, and a spring means for holding said carriage and the knife mounted thereon at the top end of said track before operation is started.
13. A device according to claim 12, wherein said device comprises a casing and said spring means comprise two tension springs, one spring being arranged on each side inside said casing and attached with their one end to the walls of the casing and with their other ends to the carriage.
14. A device for detaching a strip of gummed tape from a reel, which comprises a guide track for said strip, a hand-operated carriage adapted to slide upon said track, a curved knife with a bent-down point, a support for said knife mounted for rotation on said carriage, said knife being exchangeably attached to said support and capable of feeding said strip from said reel over said track, said track having an end face adjacent to a transversal slot, said end face and slot being adapted to cooperate with the point of said knife in severing the strip, and spring means for holding said carriage and the knife mounted thereon at the top end of said track before operation is started.
15. A device according to claim 1, said track comprising a bottom and a plate underneath the same, said plate having formed thereon lateral portions bent upwardly and forrrlring side rails for guiding the strip of tape on the trac'.
16. A device according to claim 15, wherein said plate consists of a transparent material.
17. A device according to claim 1, comprising a member arranged on the track for limiting the upward movement of the knife thereon.
