Roller And Pod Patents (Class 139/295)
  • Patent number: 6915822
    Abstract: A fabric spreader arrangement for a loom includes a spreader rod rotatably received in a hollow space of a spreader body. The fabric is looped around the spreader rod in the hollow space. To achieve a low wear, a light weight, and an excellent fabric spreading effect, the spreader rod is a one-piece hollow cylindrical metal body extending entirely over the weaving width, preferably made of V4A stainless steel, having an outer diameter of at least 10 mm (and preferably 15 mm) with a wall thickness of at least 0.4 mm (and preferably 0.7 mm), and having an outer circumferential surface that has been surface treated to achieve a surface roughness with a peak-to-valley roughness measurement of at least 10 ?m (and preferably 20 to 50 ?m).

  • Patent number: 5052447
    Abstract: A guide device for a web of material at a point of a textile machine, preferably a weaving machine, at which the web of material is produced. The guide device includes a first guide strip with a guide edge which first guide strip is arranged subsequent to the point at which the web of material is produced and a second guide strip with a guide edge which second guide strip is arranged subsequent to the first guide strip. The guide strips extend in each instance along the entire width of the web of material and overlap one another in such a way the web of material is guided at least approximately in an F-shaped manner. The guide edge of the second guide strip is formed by a rotatable round bar. The rotatable round bar is arranged in a loose manner in such a way that is is supported, under the influence of the tensile stress of the web of material, along the web of material at the first guide edge and in direct contact at the end face of a guide element of the second guide strips.
