Description
1 ~77457 BACK~ROUND OF THE INVENTION
The use of twist tie ribbon for securing the neck o~ a plastic bag or other item is expanding very greatly. So man~
ties are used that it has become economical to carry out the closing operation with a powered twister~ the twister being powered either by electrlcity or air. Where the ribbon is applied by hand it has been traditional ~o sell the ribbon in uniform cut lengths. Whe~e the ribbon is tied with an automatic device, the device itself cuts~ ~eeds and twists the ribbon. The twister can exert enough pressure on gripper feed wheels to pull and unwind the ribbon from its large wound spool~
,i ~ ~77457 Recently, ~wo mechanical twisters have been introduced in the market, ~he twisters belng manually operated and powered. A new problem has arisen due to ~he difficulty o~
applying sufficien~ gripping power ~o pull and feed ~he ribbon without slippage from the spool upon which it is wound~ It is anticipated that this problem will become even more severe as attempts are made to develop manua}ly-powered equipment to operate at higher speeds and with stiffer ribbon. The present invention is intended to overcome this difficul~y without o increasîng the effort required of~the operator thereof.
SUMMARY OF TH~ INVENTION
The twist tie ribbon of the present invention has indentations ~hereon designed for reducing or eliminati~g the slippage between the ribbon and grippex ~eed wheel in 8 mechanical twist tie twlster~ To accomplish this purpose the twist tie ribbon whether of standard extruded construction or of laminated construction has indentations thereon whir~h mate with a correspondingly shaped feed wheel or wheels.
Breferred indentations are in the shape o corrugations or knurling. The metal wire running along the center of the strip may be either straight or corruga~ed.
~cca~d~ngl~, the present in~ention xel~tes to I F77~57 twist tie ribbon which can be used in combination with a manually operated mechanical twist tie twister and in which slippage between the ribbon and gripper feed wheels is minimized.
More specifically the invention relates to a twist tie ribbon construction for use in combination with a mechanical twister having first and second opposing rotatable feed wheels for the feed of such rib~on there-through from a supply spool, comprising a twist tie ribbon having a predetermined pattern of indentations on the opposed surfaces thereof repetitively uniform along the length of the ribbon and defining a gripping pattern for interengagement ~ith the twister first and second feed wheels, the surface pattern being shaped to interengagingly mate with a correspondingly shaped pattern of surface pro~ections on the feed wheels to provide requisite, non-slip gripping power to pull and feed the ribbon from its supply spool. The twist tie ribbon can be knurled or corrugated, the indentations thereon preventing slippage between the ri~bon and gripper feed wheels of a mechanical twister, with the ribbon being either of standard extruded construction or laminated construction.
Other features of the invention will in part be obvious and will in part be apparent from the specification and drawings.
The invention accordingly comprises an article of manufacture possessing the features, properties, and the relation of elements which will be exemplified in the article hereinafter described, and the scope of the invention will be indicated in the claims.
BRIEF DESCRIPTION OF THE DR~WING :
For a fuller understanding of the invention, reference is had to the following description taken in connection with the accompanying drawings, in which:
` ~ 1 77d,57 Fig. 1 is a plan view of an indented twist tie ribbon passing over a gripper feed wheel, the ribbon in this case being corrugated;
Fig. 2 is a vi~w taken along line 2-2 of Fig. 1 and showing a length of twist tie ribbon passing between a pair of gripper feed wheels;
Fig. 3 is a view ~aken along line 3-3 of Fig. 2; and Fig. 4 is a plan view of a knurled ribbon passing over a gripper feed wheel.

o DESCRIPTION OF THE PREFERRED EMBODIMENTS
As shown in Fig. 1, a length of twist tie ribbon ll passes over a gripper feed wheel 12 in the direction shown by the arrow. The ribbon has embedded along the middle thereof a metal wire 13 to provide strength to the ribbon and to hold the ribbon in place after twisting. In the embodiment shown in Fig. 1 the indentations are in the fonm of corrugations 14, the corrugations being spaced and sized t so that the ribbon mates with corresponding corrugations 16 on feed wheel 12, It is to be assumed that Fig. 1 represents 20 metal wire 13 in either straight or corrugated form and ribbon of standard extruded or laminated construction.
In Figo 2, gripper feed wheels 12 and 17 are sho~n as having channels 19 and 21 along the peripheries thereof for receiving feed wire 13 and encasement 18 thereof. Teeth 16 I ! 77457 and 18 of gripper eed wheels 14 and 17 respectively mate with corrugations 14 of ~he tie ribbon so as to provide a strong puLl without slippage.
~ he way in which thQ corrugations of twist tie r;bbon ll mate with teeth 16 and 18 is more clearly shown in the view of Fig. 3.
As aforenoted) the tie ribbon may also be knurled, and such a construction is shown in Fig. 4. Lines 21 represent knurling, and gripper ~eed wheel 22 is correspondingly knurled o to mate therewith As is evident, other patterns may also be used such as V-shaped indenta~ions or curved notches. It should be noted, however, that it is not deemed essential tha~ the pattern of the ti~ ribbon correspond to or ma~e with - the pattern o~ the gripper feed wheel teeth since the knurled or abrasive texture o~ the tie ribbon will insome applications provide sufficient gripping power to achieve the objects of the present invention.
As will be evident, the construction shown herein may be realized in paper, suitable plastics such as polyvinyl 20 chloride of appropriate flexibility and other materials~
It will thus be seen that the objects set forth above, among those made apparent from the preceding description, are efficiently attained and, since certain changes may be made in the above article without departing from the spiri~ and scope of the invention, it is intended that all matter contained in the above description and shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
