Abstract:
A floor-covering article has an upper layer with yarns that extend through a primary backing and are at least partially secured to the primary backing by polymeric material, wherein the yams define an exterior upper surface of the article; an intermediate layer connected to the upper layer; and a secondary backing connected to the intermediate layer so that the intermediate layer is positioned between the upper layer and the secondary backing. The article includes cut peripheral side edges. The length and/or width of the article can be at least about 91 cm (3 feet). At least one of the peripheral side edges of the secondary backing can define an upright, outwardly-oriented side face extending obliquely to the bottom surface of the secondary backing.
Abstract:
A method of separating strands of a slit web is disclosed. The method includes providing a slit web having a length in a machine direction and running the slit web in the machine direction onto a stretchable surface. The slit web includes multiple strands provided by a plurality of slits extending in a first direction not parallel to a cross-machine direction. The slit web is in contact with the stretchable surface for a path length in the machine direction, and for at least a portion of the path length, the stretchable surface is stretching in the cross-machine direction. The traction between the slit web and the stretchable surface during the stretching at least partially separates at least some of the multiple strands of the slit web in a second direction transverse to the first direction. A method of increasing a width of a polymeric netting is also disclosed.
Abstract:
The method for welding profiled elements in plastic material, in particular PVC, comprises the steps of: preparing two profiled elements (3; 3a, 3b; 60, 61), arranged with respective zones to be welded (4; 62, 63) facing one another; making a groove (19) in correspondence to at least one zone to be welded (4; 62, 63) of the profiled elements (3; 3a, 3b; 60, 61), the step of making the groove (19) being performed by means of a removal operation on a peripheral edge of at least one profiled element (3; 3a, 3b; 60, 61); heating the zones to be welded (4; 62, 63); coupling the zones to be welded (4; 62, 63) to one another, pressing the profiled elements (3; 3a, 3b; 60, 61) one against the other so as to keep the zones to be welded (4; 62, 63) in reciprocal contact; the step of coupling the zones to be welded (4; 62, 63) comprising: a sub-step of melting the zones to be welded (4; 62, 63) into one another in order to define a welding bead; a sub-step of making a containing compartment (19a) defined by the groove (19), the welding bead being made internally of the containing compartment (19a); and the step of arranging a containing presser (27) in correspondence to the containing compartment (19a) for preventing exit of the welding bead from the compartment itself.
Abstract:
A sampling device (10) for removing a surface portion from a substrate (112). The device includes a frame structure (16) and a cutter head assembly (12). The cutter head assembly (12) includes a pivot body (32) having a first end (42) supported at a pivot point (108) on the frame structure, and a cutter supported for rotation about a rotational axis at a second end (46) of the pivot body (32). The cutter has a semi - ellipsoidal shape (70) and a drive motor is operably connected to the cutter (70). The pivot point (108) is located in spaced relation to the rotational axis (AB). The cutter (70 is operable to cut a surface portion of a substrate (112) during pivotal movement about the pivot point (108).
Abstract:
A sectioning device including a frame having a cutter deck with an opening disposed therethrough; a removable insert having an opening disposed therethrough, the removable insert positioned above the opening of the cutter deck such that the opening of the removable insert and the opening of the cutter deck are concentrically aligned; a cutter removably positioned on the removable insert; a press assembly positioned on the frame for pushing an item against and through the cutter; and an activator moving at least one of the cutter and the press assembly between a neutral position and a sectioning position in a single continuous motion, the press assembly and the cutter configured such that the item is sectioned upon movement from the neutral position to the sectioning position.
Abstract:
A workpiece cutting apparatus (100) that basically includes a fixed blade (4), a moving blade (1) and a cleaning component (6). The fixed blade (4) is configured to fixedly receive a workpiece (9). The moving blade (1) is moveably mounted relative to the fixed blade (4), and the moving blade (1) and the fixed blade (4) are arranged relative to each other to shear the workpiece (9) that is fixed relative to the fixed blade (4). The cleaning component (6) is arranged relative to the moving blade (1) to remove a deposit from the moving blade (1).
Abstract:
This device comprises: - one support plaque (1 ) of the sheet (81 ), with windows (12) for insertion of the corners of the card (12); cutting blades (4) facing the windows (12) to be displaced through the windows (12) to provide oblique cuts (83); - a cardholder plaque (3) for fastening the card (82) in a window (34), wherein part of the contour of this window (34) is level with the route of the blades (4); pushers (5) that are moveable towards the support plaque (1 ), facing the windows (12) of the support plaque (1 ), for insertion of the corners of the card (82) through the oblique cuts (83) of the sheet (81 ); - an actuator of the cutting blades (4) and of the pushers (5) for their displacement.
