    摘要： A continuous wrapping system and a respective cutting unit are disclosed, for cutting a paper-based wrapping web continuously wound onto a plurality of wrapped products (8) spaced apart one another by a separation gap (D) and running along a sliding axis (Y-Y), comprising
    a ground support frame (T) supporting a translation assembly (S),
    a carriage (C) slidably mounted on said translation assembly (S), equipped with at least one roller conveyor assembly (R) for supporting said wrapped products (B), and
    a support frame (CT), integral in translation with said carriage (C), which defines a cutting plane,
    further comprising
    a wetting assembly (U) provided with nozzles (16) apt to spray a work liquid crosswise to said sliding axis (Y-Y), so as to define wetted areas at least on a perimeter annular band crosswise to said sliding axis (Y-Y) and in correspondence of said cutting plane.

    摘要： Described is a method of making a laminated paint roller wherein a perforated strip of thermoplastic material is advanced, the perforated strip having holes there-through. A lubricant is applied to the inner surface of the advancing perforated strip of thermoplastic material. The lubricated, perforated strip (23) of thermoplastic material is helically wound around a cooled mandrel (21) so as to form a helically wound strip (23) wherein the inner surface of the perforated strip faces the cooled mandrel (21) and the outer surface of the perforated strip faces away from the cooled mandrel. The wound perforated strip is advanced along the cooled mandrel. A layer of adhesive (25) is applied onto an outer surface of the wound perforated strip. A strip of composite cover material (17) is helically wrapped about the wound strip and over the layer of adhesive, the outer surface of the composite cover (17) material comprising a pile fabric (2), and the inner surface of the composite cover material comprising thermoplastic. A compressive force (28,28a,28b) is applied upon the composite cover material to urge the composite cover material, the layer of adhesive and strip of thermoplastic material together against the cooled mandrel, thereby laminating the inner surface of the composite cover material to the outer surface of the strip. A method of making a composite cover material is also disclosed.

    摘要： An apparatus for cutting workpieces (36) moving along a path relative to the apparatus, including a guide arm (20), a tool mount (24), and two rotation mechanisms (28), (30), is provided. The guide arm (20) includes mounted links (40), (46), and at least two intermediate links (42), (44), pivotably connected end-to-end to each other to define a multiple bar linkage arrangement. The tool mount (24) is attached to the guide arm (20) at a connection of two of the intermediate links. The rotation mechanisms (28), (30) are in communication with the links (40), (46), for pivoting the links (40), (46) to cause movement of the intermediate links(42), (44), further causing the desired movement of the tool mount (24) in the path of the moving workpiece (36). Additional components include a second guide arm (22) positioned on the opposite side of the workpiece (36). The tool mount (24) is elongated to hold multiple nozzles (58) and is pivotably connected Between the two guide arms (20), (22). In a second embodiment, the apparatus includes a carriage (82), a pivot frame (80) with a longitudinal guideway (88) capable of engaging the carriage (82), a translation mechanism for moving the carriage (82) along the guideway (88), a tool mount (24) attached to the carriage (82), and a rotation mechanism for pivoting the pivot frame (80). The combined rotation of the pivot frame (80) and translation of the carriage (82) causes desired movement of the tool mount (24) in the path of the moving workpiece (36). Additional components include a second pivot frame (100) positioned on the opposite side of the workpiece (36). The tool mount (24) is elongated to hold multiple nozzles (58) or other tools, and is pivotably connected between the carriages (82) of the first and second pivot frames (80), (100). The apparatus of either embodiment has 2 degrees of freedom, permitting a variety of available cutting patterns.
