'5 Claims. (01. 91-13) The present invention relates to strip moistening machines and particularly to the type of machine for subjecting a part of the strip to a wetting operation when the operator pulls on the strip to remove 'a part from a roll of the strip material.

In the manufacture-of rubbercrepe soled shoes, it is desirable to cover the outsole of the shoe with astripof crepe rubber. Thiscrepe rubber must betreated'so that it is tacky and will adhere to the sole of the shoe. I herefore it is desirable to .pass the strip of material through a solvent, such as benzoLso-asto cause the strip material to become tacky. Care must be taken that the rubbercrepe material do'es not remain in the solvent for too long a period, which may cause deformation anddisintegration-of the strip material.

One 'of the objects of the present invention is to provide a maohine'in which the strip material is immersed in the solvent only during the period while it is being withdrawn from the supply roll, i. e., while the operator is applying the severed strip material to the sole of the shoe, thesupply of strip material is not immersed in thesolvent but is in the free air and the solvent thereon is evaporating and creating the tackiness of the material. v

Further objects and advantages of the present invention will be apparent irom the following description, reference being had to the accompanying drawings wherein a preferred form of embodiment of the invention-is clearly shown.

In the drawings:

Fig. 1 is aside view of the strip material moistoning machinapart of the tank containing the solvent being broken away to more clearly illustrate the invention; and

:Fig. 2 is atop plan viewof the machine shown in Fig, 1.

Referring to the drawings, there is shown a work bench or table 20, the front end of which is indicated at2l and the rear at 22. The operator faces the front end 2| of the work bench. A bracket 24 at the rear of the work bench carries an axle 25 which in turn carries a roll 26 of strip material. *Thestrip material to be utilized in the manufacture of-shoes is rubber'crepe material 28, the convolutions-lof which "areiseparated by a convolute strip 1 of separating material, such as paper 29.

The rubber crepe material 28 alone is to pass through the solvent and therefore the paper 29 must be stripped from the rubber crepe 28 and for this reason there is provided a sheet metal stripper :3! which issuita'bly-carried bythe .upper frame .33. The free end of this stripper 3| .extends rearwardly and between the bottom side of the crepe material it! and the upperside of the paper29. As the materialsare moved to theleft, as viewed inFig. 1, the stripper 3] will strip the paper 29 from the material .28. The rear .part of the stripper 31 is provided with ears 32 .on opposite sides thereof to provide aguidefor the strip material 28.

A tank 34, containinga solventsuch =as benzol is supported by a plat form35 midway .between the front andflrear of the work table 20. .A portion of the crepe material .28 is to be dippedor immersed into the solvent 36in the tank 34 whenever the operator pulls upon thestrip material to withdraw the same from the roll 26. To .accomplish this, there is providedalframem which is pivotally mounted at the rear 39 on frame 33 by a hinge 40. The (front endof the frame 38 is carried by a spring '41 which isattached an: to a bracket 43. .Frame 38 is rectangular in .top plan and is provided with bearings and '46 for supporting front roller 49, and rear .roller 50,

respectively. Roller .is disposed immediately a above the tank 3'4.

The upper frame "33 isrigidly connected with the rimof tank 34 and is provided with anopening 3B toperniit=dipping of roller 50. When the frame Z38 is swung counterclockwise about its pivot 39, the lower part of roller 5D is' then dipped into the lliqiiid (3'6 the tank '38.

.A guidein the form of ardllerlil 'isinterposed between the rear of frame'38 and thestripperil.

Rear roller 5| is carried by the brackets 31 mounted on the rearo'f frame'33. -A stripguide 53, on vframeliiil is 'interposedbetween .roller "51 SI and guide ;53 under roller 50, over roller 49, under roller 55 and over roller :58. By pulling forwardly on the extreme :front end .6! .of the crepe strip 28, the roller 26 will be unwound and due to the-friction offered by the .rollers .50, 5|, 53 and 26, tension will be imposed on the strip of material intermediate the roller 50 and the front section 6| thereof. This tension will be sufficient to cause the frame 38 to be moved ina counterclockwise direction about the pivot 39 and the section of the crepe material adjacent the roller 50 will be immersed in' the solvent 36. After the desired amount of material is pulled forwardly over roller 58, the operator will cut oif the desired length and then release the end section fil The releasing of this. end section will release the tension of the section between roller 50' and the end section N with the result that the spring 4| will lift the frame so that the. roller 50 and the section, which was previously immersed, will be lifted out of its contact with the solvent 36. The time period for pulling out sufllcient material to form the desired length of strip to be applied to the shoe,is of sufilcient duration to adequately wet the crepe material with the solvent, and, the time period from when the material is withdrawn from the solvent, upon the subsequent pulling and cutting operations, is of sufficient duration to effect desired tackiness so that it will adhere to the crepe sole of the shoe. It will be understood that the tension of the spring 4| is such that it will support the frame and it's rollers out of contact with the liquidwhen no tension is applied to the strip material 28 and that the spring will yield sufficiently to the tension created by the strip pulling operation to permit immersing of the lower part of the roller 50 and the strip therebelow.

From the foregoing, it will be seen that it is necessary only for the operator to pull forwardly on the strip'to effect the immersing of the strip and that the immersing takes place only during the pulling operation. Thus the withdrawing of the desired length of strip from the roll 26 and theapplying of solvent to the strip is carried out in one single operation.

' While the form of embodiment of the present invention as herein disclosed constitutes a preferred form, it is to. be understood that other forms might'be adopted, all coming within the scope of the claims which follow.
