[0004]The adhesive that is applied during the manufacture using the tufting process must be dried, for which purpose a large quantity of energy and time is required, and whereby, depending upon the type of adhesive, more or less noxious vapors are released. The loops of the pile threads leave a certain amount of pile material, as a function of the thickness of the threads or yarns, in the back side of the rug or carpet, as a result of which the ratio of the

Example

[0014]Referring now to the drawings in detail, a carpet or rug manufactured using the tufting process is comprised of a woven base or spun fabric, a tuft support or substrate 1, into which are tufted pile threads or filaments 2 on a multiple needle machine. Above the tuft substrate 1, the pile threads 2 form a pile layer 3 having the height a in FIG. 1. The loops 4 of the pile threads 2 are pierced through the tuft substrate 1 and must be held securely in place.

[0015]Pursuant to the state of the art of FIG. 1, the pile binding is effected in that a layer 5 of a liquid adhesive is applied onto the underside of the tuft substrate 1, together with the pierced-through loops 4 of the pile threads 2; the layer 5 covers the tuft substrate 1 and encases the pierced-through loops 4 of the pile threads 2. To cure the adhesive, the coated carpet is heated, whereby the volatile material present in the adhesive evaporates. This thermal treatment involves an increased expenditure of energy and ti...

Abstract

A method of producing a carpet or rug pursuant to a tufting process, including tufting pile threads into a tuft substrate, and guiding the back side of the tuft substrate along while pressing the back side, together with the loops of the pile threads pierced through the tuft substrate, against a heated drum. At a predetermined temperature, the loops of the pierced-through pile threads begin to melt, and at a predetermined pressure are pressed flat against the tuft substrate.

Description

[0001]The instant application should be granted the priority date of 24 Oct. 2006, the filing date of the corresponding German patent application DE 10 2006 050 704.5.BACKGROUND OF THE INVENTION[0002]The present invention relates to a method of producing a carpet or rug pursuant to a tufting process, and also relates to a carpet or rug produced pursuant to such a method.[0003]Carpets or rugs manufactured using the tufting process serve primarily as design goods for flooring, for floor coverings in vehicles, or for similar purposes. In order to hold the loops of the pile threads that are pierced through the tuft substrate securely in place during the tufting process, a liquid or plastic, synthetic or natural adhesive / binder or latex is applied to the underside of the tuft substrate.[0004]The adhesive that is applied during the manufacture using the tufting process must be dried, for which purpose a large quantity of energy and time is required, and whereby, depending upon the type of...
