Disclosed herein are various forms of hybrid baseball bats comprising a wood shell having a radial wall and an outer radial surface profile defining a baseball bat. The wood shell having a central core with a central surface thereon extending from a distal end of the bat. The central surface being profiled with a taper that in some embodiments extends entirely through to the proximal end. A fibrous construct is housed in the central core and infiltrated with an epoxy resin. In some forms, the fibrous construct is in the form of a sleeve. Disclosed are various manufacturing techniques for manufacturing hybrid baseball bats including a low pressure bladder method, a high pressure bladder method, and a centrifugal force method.

The present invention relates to a method and a system for manufacturing a board body (10), such as a skateboard, from a blank (20) having an indefinite shape. The blank (20) with the indefinite shape is collected by a handling robot (50). The shape of the blank (20) is scanned in three dimensions by means of a vision system (47) and a virtual image of said blank (20) is stored in a memory and used to calculate a three dimensional cutting path for milling the blank (20) into said board body (10).

In one instance, the disclosure is a multilayered ball bat comprising multiple sheets of wood or other material. The sheets of wood can be uniform in thickness and are bonded together with adhesive. The sheets can also be made of fiberglass-reinforced wood. The sheets run the length of the bat, from the end-cap to the knob. The sheets are planar and run parallel to each other. Each sheet has two terminal sides. When the sheets are bonded together, the terminal sides form the hitting surfaces of the ball bat. The ball bat can also have multiple layers of different varieties of wood, with a less dense wood making up the top and bottom layers of the ball bat and a denser wood making up the middle layer of the ball bat. By using multiple sheets of uniform thickness, the ball bat is more break-resistant with an acceptable weight for swinging.
摘要:
A manufacturing method of wooden rod with central hollow. The manufacturing method includes steps of: preparing a wooden material with a predetermined length and a predetermined minimum outer diameter; axially drilling the wooden material from one end to the other end to form a shaft hole; fitting a reinforcing material into the shaft hole; and locating the wooden material with an axis of the shaft hole as a rotary axis and milling a periphery of the wooden material to form a rod/bat body with a predetermined shape.

An apparatus for servicing and repairing cues including a collet mounted to a rotation member and having a collet body defining a passage including a generally conical surface, at least two collet jaws formed of a flexible resilient material and slidably disposed within the passage to define arcuate gaps with the surface, and an adjuster for slidably moving the collet jaws to flexibly bear against a cue inserted through the collet. A cutter feed includes a mounting to a bed proximate to a headstock for movement parallel to the bed. A cue tip shaper mounted to the cutter feed and having a rotatable arm for shaping a cue tip to a preselected curvature. A flexible resilient sleeve rotationally mounted to a support for holding a cue by frictional contact. A pivot mount for mounting a motor to the bed in a first position proximate to the support and pivotable to a second position proximate to the headstock. A pincers press mounted for sliding movement along a guide way to pinch and smooth wrap on a cue. An iron mounted for sliding movement along the guide way to apply heat and pressure to wrap on a cue. A cue tip holder for mounting to the cutter feed and having at least one resilient finger adapted to hold a cue tip for attachment to the cue.

A hockey stick curving apparatus which includes a rail having a first end, a second end, and an exterior surface. A movable pressure member support frame is mounted to the exterior surface of the rail and movable between the first end and the second end. A pressure member is mounted to the pressure member support frame and movable in a first direction toward the rail and in a second direction away from the rail. A pair of supports are secured to the rail in spaced relation. One of the pair of supports is on one side of the pressure member support frame and the other one of the pair of supports is on an other side of the pressure member support frame.

At least one end surface of a racket frame is occupied by a wooden shell layer obtained by transversely slicing a given elongated wooden material. Transmission of shock on the playing face onto user's hand holding the grip section is well hindered, and development of cracks and generation of wooden burrs are well prevented at drilling of through holes for strings.
摘要:
A machine for cutting a ''checkering'' pattern or other ornamental pattern in a gun stock or other structure by means of one or more cutter structures having cutting edges shaped in correspondence with the desired pattern, with the machine acting to produce relative vibratory movement of the cutter structure and work piece, and preferably also relative oscillatory movement in a second direction, and in a controlled manner very positively and effectively forming the pattern in the work piece.
