  • Patent number: 5752357
    Abstract: A method for a temporary attachment of a covering on a base, for example, a floor covering or a wall covering, is disclosed. The method includes the steps of: treating a base for supporting a covering with a material containing a particulate subject to a magnetic attraction or a magnetically-attracting particulate; producing the covering for attachment to the base so that the covering contains a magnetically-attracting particulate material or a magnetic attraction particulate, the particulate of the covering being different from the particulate of the base so that the covering and the base are magnetically-attractable to one another; and, placing a side of the covering against the base so that the covering is temporarily attached to the base by magnetization and without an adhesive. A surfacer material or a precoat, which magnetically-attractable material, may also be applied to the base.

  • Patent number: 5529002
    Abstract: In the context of an apparatus for the manufacture of patterned tufted fabric comprising a needle bar, which has a transverse member extending right along its length, on which a plurality of rotatably mounted needle carriers are arranged in a row, which respectively bear several radially projecting needles for threads and by means of a swiveling device are able to be moved into stitching positions, it is possible to attain a high degree of accuracy and a compact construction if the swiveling device associated with each needle carrier, which is able to be locked by means of an abutment device in the stitching positions of its needles, possesses an associated transmission element able to be actuated by an associated drive device and in mesh with a segment provided on the needle carrier side, or if the needle carriers are designed a rotors of disk rotor stepper motors arranged in a row on the transverse member, respectively having a disk-like stator which is stationary in relation to the transverse member and at

  • Patent number: 5357886
    Abstract: In the case of an apparatus for the production of textile pile fabric, and preferably for the production of two bilaterally symmetrical webs of textile pile fabric, comprising a conveying device, able to be driven in steps, for at least one taut support fabric web, with at least one tufting needle bar extending athwart the direction of web conveyance and which bears a plurality of tufting needles placed with a mutual spacing and is able to be moved transversely in relation to the plane of web conveyance, the tufting needdles entraining one respective pile thread and piercing each support fabric web to form a pile thread loop and a loop holding device which is adapted to be reciprocated, is arranged opposite to the tufting needle bar, plunges into the pile thread loops, and preferably places a binding thread therein and in the case of the production of two bilaterally symmetrical textile pile fabrics the conveying device receives two support fabric webs held taut with a distance apart equal to the sum of the i
