A unitary elastic mold and cutter combination configured to mold and cut moldable material is disclosed herein. The mold and cutter combination comprises an elastic mold cavity having an elastic bottom wall with an embossed inner surface and an elastic sidewall extending from and unitary with a perimeter of the bottom wall. An elastic cutting blade extends from and is unitary with the sidewall of the mold cavity and is configured to cut moldable material and maintain a substantially consistent perimeter upon cutting. The cutting blade comprises a cutting edge disposed between an inner cutting blade surface and an outer cutting blade surface. The mold and cutter combination may have an elasticity sufficient to release molded material therefrom by hand stretching, wherein the cutting edge, inner cutting blade surface, and the inner surface of the sidewall of the mold cavity are stretched by an amount sufficient to release the molded material.

A method of manufacturing a sole structure includes providing a plate within a cavity of a mold. The plate includes a base and a rib, and the base includes a first surface and a second surface. The first surface faces the upper, the second surface faces away from the first surface, and the rib projects from the second surface of the base. Moreover, the method includes providing a preform bladder member within the cavity of the mold, wherein the preform bladder member including a first member and a second member. The method additionally includes forming a bladder from the first and second members using the mold. Also, the method includes attaching the first member to the plate using the mold. Attaching the first member to the plate includes shaping the first member according to surfaces of the rib.

A method for producing a pipe assembly which has a base body with at least one channel, wherein at least one functional element is allocated to the channel. The functional element is arranged on a tool carrier, the tool carrier is inserted between blow molding tools of a blow mold, a tubular preform is introduced into the blow mold and is put over the tool carrier with the functional element, the blow mold is closed and the pipe assembly is produced from the preform by blow molding. The functional element is connected to the pipe assembly in a materially bonded and/or form-fitting manner, and the tool carrier is equipped with at least one cutting edge, wherein the blow molding tools bear against the at least one cutting edge when the blow mold is closed and press off the preform so that a separation region is formed.
