A method and apparatus for mounting and tightening an open clamp about an object to be fastened in which a first jaw-like member causes the band end portion intended to constitute the inner band portion to be placed about the object to be fastened, a second jaw-like member then causes the other band end portion of the clamp intended to constitute the outer band portion to be placed about the object to be fastened in such a manner that the outwardly extending hook or hooks in the inner band portion is or are adapted to engage with the corresponding aperture or apertures in the outer band portion. Two further jaw-like members each having pincer-like nose portions at the free ends are then actuated to engage with the outwardly extending leg portions of a plastically deformable ear in the clamping band to plastically deform the latter after the mechanical connection by engagement of the outwardly extending hook or hooks in the corresponding aperture or apertures is established, to tighten the clamp about the object to be fastened. A holding device thereby holds the clamp in position until the first and second jaw-like members have been actuated and assume the holding function to permit release of the clamp by the holding device. Operation of the machine is fully automatic by appropriate sequence controls of fluid-actuated piston and cylinder units.
A machine for automatically affixing onto an object to be fastened thereby an open clamp structure formed by clamping band means having at least one outwardly extending hook means within the area of the clamping band means intended to form an inner band portion, at least one corresponding aperture means for engagement by said hook means and located within the area of the clamping band means intended to form an outer band portion overlapping the inner band portion when the clamp structure is installed about the object to be fastened thereby, and tightening means in said clamping band means for tightening said clamp structure about the object to be fastened thereby, said tightening means being located in said clamping band means on the side of said aperture means opposite the free end of the outer band portion, comprising
A method for automatically mounting and tightening an open clamp with band portions intended to form inner and outer band portions about an object to be fastened, comprising the steps of firmly holding the clamp, engaging the band portion intended to constitute the inner band portion to place the same about the object to be fastened, thereafter engaging the band portion intended to constitute the outer band portion in such a manner that a mechanical connection including at least one hook in the inner band portion is adapted to engage in a corresponding aperture provided in the outer band portion, releasing the previously held clamp, now held about the object to be fastened, and thereafter plastically deforming an ear provided in the outer band portion to tighten the clamp about the object to be fastened.
