  • Patent number: 7971687
    Abstract: An elevator load bearing assembly (20) includes a plurality of cords (22) within a jacket (24). The jacket has a plurality of grooves (32, 34, 36, 38 40) spaced along the length of the belt assembly. Each groove has a plurality of portions (50, 52, 54, 56) aligned at an oblique angle (A, B) relative to a longitudinal axis (48) of the belt (20). In one example, the grooves are separated such that there is no longitudinal overlap between adjacent grooves. In another example, transitions (60, 64) between the obliquely aligned portions are at different longitudinal positions on the belt. Another example includes a combination of the different longitudinal positions and the non-overlapping groove placement.

  • Patent number: 7361007
    Abstract: Tubular-shaped flexible members for air springs are made of rubber or rubber-like elastomers and are reinforced by reinforcement layers. In order that the air spring flexible member can roll telescopically off a roll-off piston, the tubular-shaped flexible member sections must be brought into a slightly conical or bottle-like configuration and then vulcanized in this form. A method forms and vulcanizes an air spring flexible member blank and utilizes an apparatus which includes a mold defining a bellied inner wall defining a common hollow space for receiving the air spring flexible member blank therein. A pressure bellows unit includes a pressure bellows extending axially in the common hollow space as well as first and second end pieces joined to the pressure bellows at corresponding longitudinal ends thereof.

  • Patent number: 7267152
    Abstract: An arrangement (1) for guiding individual reinforcement filaments (2) onto a carrier (3) has a positioning disc (4) with a plurality of filament guides (9) arranged distributed on a circular ring of the positioning disc (4). The carrier is moveable in the direction of the carrier axis (X). The arrangement also includes a rotationally symmetrical deflecting element (5). The positioning disc (4) and the deflecting element (5) each concentrically surround the carrier (3). The deflecting element (5) is mounted within the positioning disc (4) and aligned axially to the positioning disc (4). The inlet-end peripherally extending inner edge (6) of the deflecting element (5) faces toward the carrier (3) and is curved. The filament guides (9) open directly at the curved inner edge (6).

  • Patent number: 6868747
    Abstract: A linear drive includes a toothed belt (2) driven by direction-changing rollers (1) in the pretensioned state. The toothed belt (2) has at least one tension reinforcement. The teeth (3) of the belt (2) engage in the teeth gaps (4) of a linear toothed counterpiece (5) over a specific length. The pitch of the teeth (3) of the belt is slightly less, up to 0.8%, than the pitch of the toothed counterpiece (5) in the pretensioned state of the toothed belt (2) and during loading of the toothed belt which occurs during operation under load. The tooth flank (6) of the tooth (3) of the belt is at right angles or almost at right angles to the plane of the tension reinforcement (7) and the tooth gap (4) of the toothed counterpiece (5) is approximately 20% to 80% wider than the width of the tooth (3) of the belt. The belt teeth (3) are elastically configured compared to the high stiffness of the tension reinforcement (7).
