The current inventive technology described methods and apparatus for the production of a helium-free balloon having customizable reflective features.

A device used to assemble a circuit module and a battery in a ball includes a battery that is not fixedly connected. The manufacturing method includes that the interior of the ball body is formed by high temperature vulcanization and wrapped by an external layer, then the battery is pushed through the normal-close elastic assembly hole of the elastic cover to the battery assembly position.

Methods for manufacturing a panel for a ball, in particular for a soccer ball, as well as panels manufactured by these methods and balls with such panels. A method comprises the following steps: providing a carrier material having an outer side and an inner side within a mold having at least one first and at least one second mold part. Three-dimensionally molding an outer layer of the panel on the outer side of the carrier material within the mold. Three-dimensionally molding an inner layer of the panel on the inner side of the carrier material using at least the first mold part.

A method for forming a plurality of panels, which may comprise cutting a plurality of Polyurethane (PU) layer cutouts corresponding to a respective shape for each of the plurality of panels from a sheet of PU, placing each of the plurality of PU layer cutouts in a corresponding mold, forming each respective panel in each respective corresponding mold by injecting melted TPE into each of the corresponding molds for thirty to forty seconds, and creating a bladder valve panel by inserting a valve in one of the plurality of created panels. Method may further comprise forming a pre-finalized ball by attaching the plurality of the panels including the bladder valve panel to a bladder and respective edges to each of the plurality of the panels to respective edges of adjacent panels of the plurality of the panels, and placing the pre-finalized sports ball in a mold and applying heat to the pre-finalized sports ball.

A ball is provided forming an inside structure of the snow person, the ball having an inner and outer surface. The ball is a unitary work piece that is free and unconnected to other work pieces. An adhesion surface is disposed on the outer surface of the ball, the adhesion surface provided with nodules that extend away from the surface of the ball to adhere snow while the ball is rolled. Light units are integrated into the surface of the ball and having light emitting portions that extend away from the surface of the ball. A light output of the light units is selected to transmit light through a layer of snow. Connections between the light units situated within the ball connect the light units together.

The invention relates to the method of producing toy balls for pets, including: manufacturing distorted sphere balls with an opening in the distorted area using injection molding; sealing the opening of the distorted sphere balls to form uni-body sphere-shaped balls. The material used in the production of these toys can be rubber, thermoplastic elastomers, or thermoplastic rubber. This method allows to manufacture toy balls with no detached parts in the case of broken joints when the balls are chewed or torn apart by the pets. Thus, the invention can help to keep the pets from endangering themselves by swallowing detached parts of pet toy balls.

A process for manufacturing a non-degumming, seamless and surface-laminated basketball, comprising the steps of: step 1: wrapping the inner bladder by threads, thereby shaping the carcass; step 2: preparing the uncured foamed middle bladder; step 3: preparing the half-finished PU surface-laminated ball; step 4: placing the half-finished leather ball obtained from step 3 into a curing mold; subsequently, curing under low temperature and low pressure via the thermal cross-linking method, thereby forming the cured PU foamed basketball; Step 5: testing the air-holding performance of the PU foamed basketball being cured under a low temperature and mounting the air nozzle, thereby obtaining the finished basketball; by means of the present invention, the prior curing process of the middle bladder and related downstream process can be saved.
