  • Patent number: 6881290
    Abstract: The printed web of paper, from which label booklets are formed, is provided in a punching unit with punch cuts, which form at least one row of punched areas and non-punched areas, wherein the punched areas remain joined to the non-punched areas respectively along a line running in the transverse direction of the web of paper. In the folding unit each punched area is deflected out of the plane of the web of paper by a blast of compressed air, is folded over contrary to the running direction by means of a pressure roller and pressed onto the associated non-punched area. In the laminating unit a transparent web of plastic provided with a self-adhesive coating on its underside is laminated over the folded web of paper and pressed so that a multilayered web is formed, which on its underside lies on a support web, which is provided with an anti-adhesive coating on its side facing the web of paper.

  • Patent number: 6350339
    Abstract: A non-stretchable wound dressing has a flexible, non-stretching cover sheet having adhesive on one side thereof, and having two spaced strip-form gripping tabs at opposite ends thereof. The cover sheet covers a urethane wound dressing with the adhesive of the cover sheet being in contact with the urethane, and the urethane having an adhesive layer on an opposite side thereof. For storage and prior to application to a patient, the adhesive of the urethane wound dressing is in contact with a releasable surface of a carrier, such as cardboard. For application to a patient, one of the cover sheet gripping tabs is pulled so as to release the cover sheet and wound dressing from the carrier, the cover sheet preventing stretching of the wound dressing. The combination is then applied to a patient, again the cover sheet preventing stretching of the wound dressing.

    Abstract: A process for manufacturing individual layered structures and the structures themselves. A continuous layered structure is provided. The continuous layered structure has designated cutting regions and includes a particulate material between the layers. At least one of the layers is permeable to liquids. A thermoplastic material in liquid state is applied to the continuous layered structure over at least part of the designated cutting regions to provide the designated cutting regions with a joining means. The thermoplastic material is made of natural or synthetic polymers, or mixtures thereof. The thermoplastic material has a softening point, as measured according to the ASTM Method E 28-67, lower than 120° C.; a viscosity at 130° C. lower than 0.05 Pa.s; and a temperature range in which the viscosity changes between 0.05 Pa.s and 0.35 Pa.s which is greater than 5° C. The thermoplastic material is allowed to set.

  • Patent number: 6217697
    Abstract: A method for producing and coating melt portions includes two sheet strips, which form coating material layers, being continually fed. The melt portions embedded between the sheet strips are cooled and calibrated according to their thickness. The sheet strips are longitudinally and transversely separated in the region of their connection points such that the melt portions become isolated and the sheet strips are connected to each other such that each melt portion is embraced tightly.

  • Patent number: 6175997
    Abstract: A method of assembling strings of pocketed coil springs into an innerspring core which may be used as the core of a mattress, cushion or similar body support foundation uses plastic netting reinforced nonwoven webs supplied between a pair of spaced apart heated rolls. Strings of pocketed coil springs are fed in seriatim into the nip between the rolls to heat the netting and activate an integral adhesive to bond the webs to the top and bottom surfaces of the pockets of each string. The core formed thus has reinforced webs on the top and bottom of the strings. The process overcomes the problems encountered when hot melt spraying is utilized to bond the pocketed coil strings together.

  • Patent number: 6171432
    Abstract: A novel method for manufacturing a layer of a laminated, disposable absorbent product, such as a fluid-permeable cover layer, an absorbent core layer or a fluid-impervious backing layer thereof, with a comparatively small amount of waste matter. The method comprises the steps of longitudinally cutting a continuous web of starting material according to a cyclic pattern constructed with line segments corresponding to the edge contour of the disposable absorbent product. The cutting operation divides the continuous web in two strips, each strip having a patterned longitudinal edge whose outline corresponds to the cyclic pattern. The strips are crossed and joined to one another in a parallel and in a phase relationship to form a compound web having longitudinal edges producing repeatedly the edge contour of the disposable absorbent product.

  • Patent number: 6123796
    Abstract: A combination of a preprinted pressure sensitive label and an electronic article security system target is provided, preferably as a supply of labels on a backing material web with the target between. The labels preferably extend about at least about 1/8th inch around the edge of the target to directly adhere to the products. Articles may be selectively marked with targets so concealed to deter theft with fewer targets. The combinations may be formed by applying first the target, then the label, to the article. Preferably, label and target combinations are supplied on a web and are then applied to the products. Combination label and target supplies may be formed by separating the preprinted labels from their backing material webs, applying the targets to either the label or the backing material, and then combining the label with either the same backing material web or a different one.
