A baseball/softball comprises a core and a cover, wherein the core is wrapped with a layer of fiber material, and the layer of fiber material is wrapped and glued with the cover. A method of processing baseball/softball comprises wrapping the core with the layer of fiber material, placing the core and the layer of fiber material into a cover material, placing the core, the layer of fiber material outside the core and the layer of cover material outside the layer of fiber material into a mold; molding the layer of cover material into the cover through a vulcanization process, gluing a vulcanization melting layer formed on inner wall of the cover to the layer of fiber material, and finally taking the finished product out of the mold. From the perspectives of smell, touch and visual sense, the product has good simulation effect of baseball/softball and better service effect.

A golf ball aligning device comprises a shaft having a first and a second end, a handle mounted to the first end and a head member mounted to the second end. The head member further comprises a ball opening extending through the height of the head member having a chamfered or rounded bottom edge to engage a golf ball. An alignment grid on the top face of the head member comprises a crosshair pattern centered with the ball opening. A golf ball engaged with the bottom edge may be manipulated and oriented relative to the alignment grid for setting the trajectory of a shot.

Provided is a golf ball liner for rapidly and exactly printing, on a golf ball, a putting line or a mark indicating the owner of the ball. The golf ball liner includes a housing having an inside space in which a golf ball is accommodated, a moving part mounted on the housing and configured to move toward or away from the golf ball, a supporter mounted in an inside space of the moving part, a stamp supported by the supporter and configured to move with the moving part and the supporter to print a putting line or mark on the golf ball, and a first detachable part formed on each of the stamp and the supporter and configured to couple or separate the stamp to or from the supporter.

This invention is about a digital printing method of cover sheet of a flexible material of required features of density, flexibility and thickness. This method includes steps of printing a cover sheet of woven or non-woven fabric, by using digital or computerized printing techniques, either direct printing or by transfer paper printing or sublimation printing technique. The printed side of the cover sheet is laminated or coated with a clear film of flexible transparent material like polyurethane, thermoplastic polyurethane, polyethylene or polyvinylchloride. This laminated or sealed printed and coated cover sheet may be fixed to different fabric, foam or of outer surface layer of an article at which printing is required. The said article may be sport's good, sport's wears, dresses, footwear, furniture covering sheets and vehicle items covers etc. The novel method of making cover sheet enables customized printing at required articles at user request with many design printing possibilities. While use of water based ink for digital printing provides an environment friendly, efficient, and durable method of printing the cover sheets of these products.

A method for forming a tennis ball including the steps of providing a non-foamed thermoplastic core and providing a non-smooth textured surface on the core. The thermoplastic core including a thermoplastic material having a specific gravity of 0.86 to 1.38, a flexural modulus of 2.0 to 50.0 MPa, and a Shore D hardness of 10 to 70. The thermoplastic material having a thickness between 3.0 and 8.0 mm. The thickness of the thermoplastic material being configured to maintain dimensional stability at internal pressures of between zero and 15 psi.

Methods for coatings for golf balls, particularly golf balls having thermoplastic polyurethane covers, and the resulting finished balls are provided. The coating is preferably a topcoat comprising a polyurethane composition containing optical brighteners. The topcoat composition preferably comprises a low concentration of optical brighteners. For example, the concentration of optical brightener can be in the range of 0.01 to about 0.20 weight %. The optical brighteners provide the desired brightness to the golf ball without sacrificing color stability. Multi-piece golf balls having inner cores, outer cores, inner covers, and intermediate layers can be made. The finished ball with the topcoat has many advantageous physical and playing performance properties.

A sport ball includes a casing that includes a plurality of joined panels and defines a cavity. The casing includes at least a first panel having (a) a first layer positioned to form a portion of an exterior surface of the sport ball, (b) a second layer disposed adjacent to the first layer, and (c) a third layer disposed adjacent to the second layer. The first panel defines a first indentation and a second indentation spaced apart from the first indentation. The first indentation has a first depth and the second indentation has a second depth that is less than the first depth. The first depth is from 0.5 times to 4 times larger than the second depth. The sport ball also includes a bladder disposed within the cavity.
