@TTG/ENE YS 3,677,429 METHOD F SEAMlNG CARPETING WITH A TAPE Robert I. Corrigan, Hazardville, Conn., assigner to igelow-Sanford, liuc., a corporation of Delaware Filed Apr. l1, 196?, Ser. No. 2l,l7l} 3 Claims. (Ci. 156-459) The present invention relates to improvements in carpet searning tapes and method of seaming carpet therewith. lt relates, more particularly, to a tape for seaming carpeting which has a padof backing or cushioning material attached thereto and forming a part thereof and a method of forming a seam joining two sections of cushioned carpeting with such a tape.

An object of the present invention is to provide a tape which will facilitate the forming of a neat, smooth seam between adjoining sections of carpet having a cushion or pad attached thereto. Another object of the invention is to provide a tape for forming a seam between adjoining sections of carpeting having a cushion or pad attached thereto which will insure that thickness of the carpeting at the seam is the same as the remainder of the carpeting. A further object of the invention is to provide a method of forming a seam between adjoining sections of cushioned or backed carpet in such a manner that an inconspicuous seam is obtained with the searned area supported by a cushion or pad of the same thickness as the pad attached to the carpet.

Other objects and advantages of the present invention will become apparent and be better understood from the following description and the accompanying drawing in which:

Fifi. l is a plan View of a carpet seaming tape embodying the present invention having portions thereof broken away to illustrate the several layers forming the tape;

FIG. 2 is an end View of the carpet seeming tape shown in FiG. l;

FIG, 3 is an end view of two pieces of cushioned carpeting joined by a seaming tape in accordance with the present invention;

FIG. 4 is an end view of a piece of cushioned carpeting prior to preparation for the seaming thereof;

HG. 5 is an end view illustrating the piece of carpeting shown in FlG. 4 during preparation for the seaming thereof and prior to being applied to a scanning tape in accordance with the present invention;

'Fi-G. 6 is a bottom View or" the two pieces of carpeting searned in accordance with the present invention as shown in FIG. 3, with a portion of the seaming tape removed for purposes of illustration.

it will be understood that the accompanying drawing illustrates the invention in a diagrammatic manner. Also, for purposes of illustration, the invention has been shown and will be described herein in conjunction with tufted carpeting il) having loops l1 forming the pile on the face thereof which are supported on a backing layer l2 of burlap or similar material to which a cushion or pad i3 or" jute or similar material is removably attached. Carpeting of this type is shown and described in detail in the copending application for United States Letters` Patent Serial No. 767,949, filed October 17, 1958, now Patent No. 3,0i9,5tl8, in the names ol Henry A. Reinhardt and David B. Parlin and entitled Cushioned Carpeting and Method or" Making the Same.

However, it will be understood that carpet seeming tapes embodying the present invention and the method of scanning carpetingr with such tapes in accordance with the present invention may be used in conjunction with other types of carpeting having a cushion or pad attached thereto which can be delaminated and removed from the back of the carpeting.

att

diligh As shown best in FIGS. l and 2, a carpet seaming tape lllembo-dying the present invention comprises a web or supporting layer i5 of a woven material such as burlap, to which a pad lo of cushioningy material, such as jute or the like, is attached. Where the web or supporting layer is made of burlap or the like and the cushion or pad is made oi jute bers, the pad may be formed on the web and attached thereto by a needling operation which may be carried out on a conventional bat forming machine in which the jute libera are compacted on the back of the web and needles force strands of the tibcrs through interstices in the web. In forming the tape in this manner, the combined thickness of the pad and the web should be approximately equal to the thickness of the cushion or pad 13 which is attached to the carpeting to be seanied so that the thickness of the seamed arm will be the same as the remainder of the carpeting and a smooth, neat seam will be obtained.

When two pices of carpeting lll? are joined together, as shown in FIG. 3, by a carpet seaming tape lll in accord ance with the present invention, the tape extends widthwise for an equal distance beneath each of the adjoining edges of the two pieces of carpeting in a space from which the cushion or pad i3 has been removed from the back of the carpeting. The opposing surfaces of the tape and. the carpeting are secured together by a suitable adhesive i7, such as a latex backiriY compound, to hold the adjoining edges of the carpeting in close abutting relation. The tape also extends lengthwise for the full length of the seam.

In preparing the carpeting ltd for seaming in accordance with the present invention, a cutis made to the depth of the cushion or pad i3 along the dotted line A, as indicated in FIG. 4, which is located inwardly from the edge of the carpeting at a distance equal to one-half th width of the tape. The portion of the cushioning pad i3 extending between the edge of the carpeting and the cut along the line A is then retrieved from the carpeting exposing the bottom of the backing layer l2 of burlap or the like.

A coating 17 of an adhesive, such as a latex backing compound, may then be applied to the exposed bottom surface of the burlap layer of the carpeting which is then brought into contact with the upperl surface of the tap-e as indicated in FIG. 5. The same procedure is followed for the adjoining piece or" carpeting and, as a result, a smooth, neat seam of uniform thickness corresponding to the thickness of the carpeting is formed.

lf desired, the adhesive coating l7 may be applied to the upper surface of the tape with the exposed bottom surfaces of the backing layer for the carpeting being brought into Contact. A coating of an adhesive which can be activated by pressure, solvent action or the like may be applied to the upper surface or the seaming tape at the tinte the tape is formed to avoid the need for ap plying an adhesive coating at `the time of fornn'ug the seam.

While the present invention has been described with particular reference to the embodiment illustrated herein, it will be understood that various changes and modifica tions may be made therein without departing from the cope of the invention as defined by the following claims.

i claim:

l. The method of `forming a seam between two pieces of carpeting, each of which has a pad oi cushioning material removably attached to the back thereof, which comprises cutting hrough the pad of cushioning material on each piece of carpeting along a line spaced from one edge thereof, stripping the pad extending between said cut and t.e edge of each piece oi carpeting from the back thereof, and then attaching a tape having a thickness equal to the thickness of the pad to the stripped back of each piece of carpeting with the tape extending between the two pieces of carpeting and holding the edges thereof in abutting relationship.

2. The method of forming a seam between two pieces or carpeting, each of lwhich has a pad of cushioning material removably attached to the back thereof as defined in claim 1 wherein the tape is attached to the stripped back of each piece of carpeting by applying an adhesive material to surfaces of the tape and the two pieces of carpeting which are in opposing relation.

3. The method of forming a seam between adjoining edges of two -pieces of carpeting, each of which has a layer of fibrous cushioning material removably attached thereto, which comprises removing a strip of the fibrous cushioning material extending along an edge thereof from the yback of each pie-ce of carpeting, and then adhesively attaching the back of each piece of carpeting from Which the strips of cushioning material have been removed to a tape which extends across and beneath adjoining edges of the two pieces of carpeting, said tape being equal in thickness to the thickness of the layer of cushioning material and being equal in width to the combined width of the removed strips of cushioning material.
