MEANS FOR BANDING PACKING CASES.

Application filed October 19, 1922. Serial No. 595,690.`

To all whom t may concern:

- Be it known that l', GUs'rAv HUGUENTN, a citizen of the Republic of Switzerland, re-' siding at Cham, Switzerland, have invented l certain new and useful Improvements in eans for Banding Packing Cases, of which the following is a full, clear, and exact description.

' This invention relates to means for pro- 19 ducing and applying endless binding hoops or bands applicable generally where such bindings are employed 4but more particularly intended for use in connection with packing cases of the kind in which merchandise such as condensed milk is contained for the purpose of transport.

The present invention has for its object to provide a device which is adapted to sever a strip of ,material of definite length 20 the material being fed, drawn or otherwise supplied from a roll or the like and to lay or apply the same about a case, container or other object ina predetermined position and in a condition of tautness andto join $5 the ends of the strip, which are caused to overlap, by welding the same together so that an endless welded hoop or band results whereof the surface is smooth and fiat there being no apparent -ridge or projection at the aforesaid point of junction and the tension. of the band is preserved.

According to this invention the device comprises a table adapted to receive and hold the case, container or other object in a predetermined or definite position and to be straddled by a length of binding strip which is fed into and along a groove or recess formed in the surface of the table. The material or strip is contained in a roll mounted adjacent to one side of the table and when a predetermined. length has been fed' or drawn from the roll the said length is severed by a suitable cutting device orguillotine. "The severed strip is then manipulated by means of a kind of folding frame consisting of hinged arms so as to bend portionsof the same against the sides 4of the case or other object and similarly the ends of the strip are 'bent over and upon the upper surface of the case or other object so as to overlap each other. The weldin of the said ends is then effected the lap extremities of the encircling stx-1p being inserted material being suiicient Figure 1 the box or between electrodes in suc-h a .manner that they rest one above the other in a flat condition and are held in that position by clamping devices with the result that a fiat portion is presented for welding which latter operation is thereby performed without unduly'` heating the binding strip at any other portion thereof. The clamping devices prevent any slackening of the strip during the operation of welding. Y

By these means the predetermined position of the binding is preserved andy its applicationeffected without destroying the tautness and close adherence ythereof about and to the case or other object.

In order that the invention may be readily understood and carried into effect, same will now be more fully described with reference to the accompanying drawings, in which :4

Figures 1, 2 and 3 are diagrammatic views illustrating the successive operations of binding the strip about the case or other object to be bound.

Figures 4 and l5 are also diagrammatic views in front elevation and plan respectively of the improved device drawn to a lar er scale.

eferr'ing first to Figures 1 to 3 inclusive the material from which the hoo or band is formed is drawn from a roll suitably mounted for rotation and the length a drawn therefrom is extended over a supporting table B which is grooved or recessed for its reception. quired which is represented b the distance between the adjustable stop Cy and the cut ting device D the latter is operated to effect the severance of the said len th from the stock contained in the roll The box,

Having obtained the length recase or other object E having been placed and positioned upon the table B the length 'of material is bent upwards along the sides of the object by turning the arms F F about their pivots f f and then by similarly turning the arm extensions F1 F1 about their pivots f1 f1 in the arms F F the ends of the said length of material arebent and brought over the top of the object the length -of to allow a lapping of the said ends one upon the other. In object E is shown 1n position with the length of strip beneath the same and extending at either side therelill of, i. e., from the cutter Dat the left-hand side to the adjustable stop C at the righthand side.` If reference be now had to Figure 2 the first stage in the binding of the strip will be observed by reason of the deection or turning of the hinged arms F F and the further bending of the strip so as to form a lapped joint is readily observable in Figure 3.

The box or object is positionedv on the table B by a block b which may be adjustable so as to admit of the band being applied at any desired distance from the side of the box or object and the table is also provided with a bracket b1 which is adapted to co-act with the aforesaid'block in holding the box or object in the desired position on the table during the application of the binding strip. The stri ma be held in the groove or recess bx in t e ta le B by means of lateral trigger springs Y or by magnets indicated at a1.

The arm extensions F1 F1 may each carryv a trigger lever f1 f1 adapted to take a bearing upon the stri see Figure 3 and to permit of the parts E1 being turned up out of contact with the' top o the box or object.

Assuming the box case or other objectto be in position on the table B with a suitable length of strip in the groove or recess Bx (Figures 4 andV 5) and the said strip' bent about the box or object as above described theclampiiig levers G G are operated by means of the handle g and right and left screw threaded spindle g1 so as to grip the said strip and force the ends of the latter into close contact the one upon the other between the electrodes H H1. By means of the handle or grip' h1 the electrode H1 is pressed into iir'm contact with the ends of the 'inding strip whereupon electrical contact is established in the primary line I of an'alternating current transformer. At this moment a current of hi h intensity and low voltage ilows through t e secondary K which is carried through the ends of the binding strip from the electrode H1 to the electrode H and thereby the ends of the binding strip are immediatel welded together over a broad surface. y now reversing the movement ofthe handle g the clamping devices lGG are released from holding engagement with the strip and the aselor object having a complete hoo or binding applied thereto may be remove Devices` for butt welding wire bindings on boxes 'or containers are known in which the 1- current is conducted through clamps but certain disadvantages arise in practice owing to a part of the current flowing through the binding and passing out ineectively as regards any 'assistance to the welding operation. The binding moreover becomes heated and the container suffers burning while the tension of the binding also suffers and' when -or bands to vpacking the latter cools upon the completion of the welding a shortening thereof takes place and not infrequently rupture ensues.

By the use of separate electrodes AH H1 which conduct the current directly to the flat lapped extremities of the strip vthese objections are obviated or minimized and the binding is preserved in a taut condition the operation being conducted without risk of the binding becoming heated otherwise than at the point of welding.
