Application filed April 3, 1926. Serial No. 99,492.

This invention relates to apparatus for handling'tacky strip material such as rubberized tape or the like.

The gener 1 object of the invention is to' provide improved apparatus Kror handling tacky strip material such asrubberized wire 'or fabrictape. i

In one particular the invention contemplates novel method and apparatus for reeling a continuous stripof tacky material.

The foregoing, and other objects are 1) taine'dby the construction and method d1sclosed in the accompanying drawings and described below. It is to be understood that the invention is not limited to the particu- =lar embodiment thereof as shown and 'described. I

,Of the accompanying drawlngsz- Figure 1 is a more orless diagrammatlc side elevation of a wire tape'insu ating apparatus embodying and adaptedto carry out the invention; Y

Figure 2 is a'front end elevatlon of the reeling device employed therein; and

Figure 3 is a detail side elevation thereof.

the drum 22 is a-level wind attachment29 comprlsln a bracket 30 riding on the usual 7 level win cam shaft'31. shaft 31 being intermittently rotated by a ratchet 31 operated by a pawl 31 on an arm 31 pivoted Q on shaft 31 andv operated b a connecting rod 31 and eccentric 31", 't e latter being on shaft 26. Bracket 30 hasa roller 32 there on under which stock 11 passes and a grooved roller 33 thereon over' which it passes. Bracket 30- also pivotally carries a 111161" strip guiding device including a grooved roller 34 over which a narrow liner strip 35 drawn from a eel 35 is passed, a plate 36 over which the liner 35 is passed, a spring clip 37 for pressing against the liner 35 on plate 36 to tension it, a roller 38 under which the liner strip asses, and finally a roller '39 for-guiding t 'e'lineiv .35 into-contact with the under side of strip 11 to be reeled on the drum therewith."

The liner guiding device is pivoted on bmcket 30at 40 and has a weight 41 on itsof drum 22 by means of an arm 42 slidably a rod 43,mounted to extend" across ,the top of brackets 23..

engagmg Drawing of the stri through the various treating devices set) orthabove is accomplished by driving one roller, such as 18 of drier 18, by means of a pulley 44 and belt 45, the. latter being trained over a pulley .46 on an. overhead drive shaft 47'.
