The combination of: a) first and second spaced pulleys; b) an endless belt; and c) a belt installation jig having a body with: a pulley pressing part; a belt holding part; and a belt pressing part. The belt installation jig and belt cooperate so that with the belt operatively wrapped against the second pulley and partially operatively wrapped against the first pulley, turning of the first pulley causes the belt to progressively wrap around the first pulley to a fully operatively wrapped state, whereupon further turning of the first pulley situates the belt installation jig for separation from the belt and pulleys.

A method and apparatus for manufacturing a duct bank comprising the steps of loading a frame with a series of templates, positioning the frame adjacent a pipe extruder, aligning a set of a plurality of holes with a die of the pipe extruder, extruding a pipe of a first length into the set of holes, repeating the steps of aligning and extruding for each set of holes, thereby forming the duct bank, banding the duct bank, and removing the duct bank from the frame.

An appliance for sealing elastic hoses with a sleeve, which is plastically deformable and slipped onto the hose, has two jaws which are movable towards and away from each other. One jaw has two straight bars which project towards the other jaw and extend transversely of the sleeve to make two transverse indentations in the sleeve and the hose when the jaws are moving towards each other. The same jaw has a cutting edge which projects towards the other jaw and is directed transversely of the sleeve, the cutting edge making a substantially transverse cutting indication in the sleeve and the hose when the jaws are moving towards each other.

A sealing fin fixing apparatus can fix a sealing fin to a rotor in a shortened period of time to minimize variations of the pullout strength of the sealing fin. In the sealing fin fixing apparatus that fixes the sealing fin in a sealing groove defined in the outer circumference of the rotor of a rotary machine and includes a headstock for setting a rotor thereon, a Z-stage movable along a Z-axis, an X-stage movable along an X-axis, a tool rest supported on the X-stage, and a caulking tool mounted on the tool rest and including a shank and a pressing roller, while the pressing roller is being held against a caulking wire inserted, together with the sealing fin, in the sealing groove in the rotor that is set on the headstock, the headstock is actuated to rotate the rotor, thereby caulking the caulking wire to fix the sealing fin to the rotor.

An apparatus is disclosed for applying tags with attached elastic anchor bands onto the tops of objects such as bottles in a high speed packaging application. The apparatus includes an infeed assembly for feeding a web, a conveyor assembly that receives a web and conveys it along a path in an upstream direction, a rotating selector wheel, a placement assembly, a pair of rotating jaw assembles, a vacuum cup of the selector wheel, and stretched elastic bands over the tops of respective bottles being conveyed along a path below the placing assembly. The elastic bands then snap onto the tops of their respective bottles to secure the tags to the bottles.

An installation tool for installing a seal includes a shaft and a seal-engaging component coupled with the shaft. During an installation of the seal, the seal-engaging component is adapted to couple with the seal. The seal-engaging component includes a first surface and a second surface. The seal-engaging component also includes a first annular ring extending from the first surface and adapted to engage with the seal for coupling the seal with the seal-engaging component. The seal-engaging component further includes a second annular ring extending from the first surface. The installation tool also includes a sliding hammer adapted to slide along a length of the shaft. During the installation of the seal, the sliding hammer is adapted to apply a force to the seal-engaging component for installing the seal at a seal installation location.

The present application discloses an apparatus for mounting an O-ring to a work piece, which includes a body including a plurality of connecting holes for connecting a pressure source to the body; an annular groove formed on the body and adapted to receive the O-ring; and a plurality of air channels formed in the body, the plurality of air channels being in fluid communication with the annular groove and the plurality of connecting holes to provide negative pressure with the pressure source in the annular groove to suck the O-ring in the annular groove, the annular groove is coaxial with a groove formed on a surface of the work piece during the mounting so that the O-ring is dropped into the groove when the pressure source is disconnected from the body or provides positive pressure to the plurality of air channels.

The present application discloses an apparatus for separating and feeding O-rings, which includes a rotatable body including a storage portion and a separating portion; and a helix groove formed on the rotatable body across the storage portion and the separating portion, wherein a width and a depth of the helix groove are adapted to a wire diameter of a O-ring, and pitch of the helix groove on the separating portion increases along a feeding direction from the storage portion to the separating portion, wherein in response to a rotation of the rotatable body, the helix groove conveys a plurality of O-rings hanged on the storage portion to the separating portion to thereby separate the plurality of O-rings away from each other.

An apparatus for mounting an O-ring to a work piece, including: a plurality of picking components operable to move away from each other to contact and expand the O-ring to pick the O-ring or to move towards each other to release the O-ring; and a guiding component including a frustum portion arranged coaxially with a groove of the work piece, a large end face of the frustum portion arranged adjacent to an end surface of the work piece on which the groove is formed, wherein a diameter of the large end face is substantially same as an inner diameter of the groove, wherein the picking components are operable to release the O-ring onto a tapered surface of the frustum portion so that the O-ring is pushed into the groove along the tapered surface.

An apparatus is disclosed for applying tags with attached elastic anchor bands onto the tops of objects such as bottles in a high speed packaging application. The apparatus includes an infeed assembly for feeding a web, a conveyor assembly that receives a web and conveys it along a path in an upstream direction, a rotating selector wheel, a placement assembly, a pair of rotating jaw assembles, a vacuum cup of the selector wheel, and stretched elastic bands over the tops of respective bottles being conveyed along a path below the placing assembly. The elastic bands then snap onto the tops of their respective bottles to secure the tags to the bottles.
