This invention relates to a method of a and means for attaching articles together, and par ticularly relates to such methods and means in connection with heat plasticizable materials.

In the construction of certain articles such as ,5 Figures 7 and 8 show the stepsin the securing chairs, loungesgetc there is often employed a of the webbing to its supporting member; covering or construction material-consisting of Figure 9 i view howing th t -1 after strips,.webs or sheets of fabrics formed of a-heat t has b Secured t t supporting b plasticizable material such as. rayon, nylon and and similar synthetic material.

(01. -187) 2 webbing wound around the supporting member and before it is secured thereto;

Figure 6 shows another manner of wrapping a strip or web around a supporting member;

metallic member, punched or pierced as at 1'6 and of substantially'the same width as the webbing I2. Preferably, the member 14 is narrower at its upper edge than its lower for permitting the folding of the fabric webbing. therearound'to improve the appearance and to give a stronger-connection.

In Figure there is shown the webbing material l2 after it has been placed on its'supportin-g member l4 and it will be noted that the corners of the webbing have been folded'down to conceal the clip l4 and also to insure a good bearing of the web on the clip. After the webbing-has been wound around the clip'="member H as shown in Figure 5, the pierced'hole at; is then made as shown in Figures 7 and 8.

The piercing is done by a pointed punch 24 which is heated toa 'temperatureat which the Webbing material l2 will become plastic and which is slightly smaller than the hole l6. For making the'hot punchefiective'it is essential that the webbing material be formed from a-thermo plastic material. Accordingly, rayon, nylon and other synthetic materials which are heat plasticizable may be employed for the webbing material. The webbing material is preferably a woven fabric but it will beapparent that the present invention is not necessarily limited to a woven material but could be practiced in connection with'sheet materiaL'ifi desired.

Returning to Figures! and8, 'the assembly shown in Figure 5 and consisting of the supporting clip member '14 and the webbing l2 wrapped the'rearound, may be placed against a die member 26 and the heated punch 24 is passed throughthe assembly into the position shown in.

FigureB. 'As the punch passes throughthe hole [6 in the clip 14, it softens the 'm'aterialof the webbing l2 andcarriesa portion of thesaid material through the hole. This -m'aterlal is softenedby'thehe'at of the punch '24 and welds with the material on the opposite sideofthe'saidmemher. and at-28 and 30.

After the punch has completely traversed the assembly of webbing and-supporting member, it is withdrawn and the resulting article is as shown in Figure-Q with asmooth surfaced aperture I6 extending therethrough. It will be'apparent that the punch 24 must be heated sufliciently to sof ten the webbing to a weldable condition and to a degree of plasticity which will permit the said material to become slightly fiuid.' Theparticular temperature at which the punch must be carried will vary for different substances and for nylon "webbing, the preferred material becausev of'its high strength andresilie'nce.

In Figure 6 there is shown the manner of placing the webbing arounda straight'clip, this type of support being "employed at the'foot of the article of furniture in Figure 1 so the webbing does'not 'pass around the end-bar of the frame an'dis thusprotectedfrom undue wear.

It will'be seen that this invention provides for a ready methodand means for securing supporting members to the ends of strips or webs, or for securing supporting member's "at different portions along'the periphery or'surface ofshee't m'aterial, the strip, webbing or sheet matenaI in This welding'is best indicated in Figures 9 each case being a thermo plastic substance and the supporting member being suficiently structurally strong to serve the purpose of a load carrying anchor.

By utilizing the means and method of this in vention the sheet, strip or webbing material can bepre'fittedwith its supportinganchors "onia mass production basis thus insuring maximum uniformity and minimum cost.

The detachable connection between the preformed webbing and the frame to which it is secured permit ready replacement of the said webbing by anyone and with a minimum of equipment. W

It will be'unde'rstood that this invention is susc'e'ptibl'e to modification in order to adopt it to different usages-and conditions and, accordingly, it is desired to comprehend such modifications within this invention as may fall within the scope of the appended claims.
