Abstract: A band clamping machine is provided for clamping a metallic clamping band having a band section, a lever for reducing an inner diameter of the looped band section, and a pair of fixing pieces for holding the lever. The band clamping machine includes a diameter reduction mechanism having a clamping arm for turning down the lever and an arm driving mechanism moving the clamping arm so as to turn down the lever. The arm driving mechanism includes a first mechanism for moving the clamping arm from an initial position to a mid position, and a second mechanism for moving the clamping arm from the mid position to a final position. A fixing mechanism is provided to bend the fixing pieces inward to fix the lever at the final position between the fixing pieces.

Abstract: A clamping band has a metallic band section with a first end, formed into a Y-shaped fork having a pair of fork pieces. A pair of concave sections are formed in each side edge of the band section. and are capable of accommodating the fork pieces. A clamping ear is formed by bending a part of the band section. The clamping ear is provided at a prescribed position at which both end sections of the band section are overlapped when the band section is formed into a loop. An engaging piece is provided in the vicinity of the Y-shaped fork of the band section. A first engagement hole is capable of engaging with the engaging piece. The first engagement hole is provided in the vicinity of the other end of the band section, whereby the band section is formed into the loop when the first engagement hole is engaged with the engaging piece.

Abstract: The present invention provides a band-clamping apparatus, which is capable of automatically clamping clamping bands wound. In the apparatus, a holding table holds a member to be clamped, which has been wound by the clamping band. A stopper prevents the clamping band on the member to be clamped, which has been held by the holding table, from moving, and the stopper is capable of contacting the holding pieces from the opposite side of a lever. A pushing arm turns the lever onto an outer face of a band section. A bending mechanism inwardly bends the holding pieces so as to secure the lever onto the outer face of the band section when the lever is located between the holding pieces. With the band-clamping apparatus of the present invention, manufacturing efficiency can be sharply raised, the clamping work can be executed safely, and the clamping strength can be maintain in the predetermined range.

Abstract: The present invention relates to a clamping band having ends, more precisely relates to one which can be attached or detached after a member to be clamped is connected to a hose, etc. and which has high clamping force. In the clamping band of the present invention, the projection of the lever can be easily fitted in the engagement hole of the band, so that the fulcrum point of the lever can be easily fitted, and clamping work including winding action and lever operation can be executed smoothly.

Abstract: A method and apparatus are disclosed for reforming the initial shape of an approximately loop-shaped starting piece into a final prescribed loop-shape. A plurality of elongated elements such as wire rods are arranged in parallel at prescribed intervals to define a prescribed looped or cylindrical space having a first diameter. A plurality of pressing means such as pressing plates actuated by cylinders and pistons press free ends of the elongated elements to reduce the diameter of the looped space prescribed by the elongated elements to define a reduced looped space having a second diameter smaller than the first diameter. The free ends of the elongated elements are then inserted within the starting piece. The pressing means are retracted, whereby the free ends of the elongated elements contact the inner surface of the starting piece.
