Impulse heat sealing of a heat-sealable film material

A sealing station configured to heat seal a wall made from heat-sealable film material, preferably metal-free heat-sealable film material, onto one another wall of heat-sealable material, e.g. another wall of heat-sealable film material, to create a sealed seam. The sealing station comprises an impulse sealing device comprising a first jaw and a second jaw, wherein at least the first jaw comprises at the respective front surface thereof at least one, e.g. a single elongated, impulse heatable member that extends along the respective front surface and that is covered by a heat-resistant non-stick covering.

GOLF BALL MANUFACTURING METHOD
20240342964 · 2024-10-17 · ·

A method for manufacturing a golf ball having a core and a cover of at least one layer includes the step of molding the cover layer with a vertically separating two-part injection mold which has a spherical cavity and three or more support pins disposed so as to be capable of advancing and retracting in a direction perpendicular to a mold parting line, each support pin being housing in a pin housing hole having a nitrided inner peripheral sidewall. This method enables a golf ball cover material to be molded using an injection mold which, because a thick plating of hard chrome does not need to be applied to the inner peripheral sidewalls of the holes housing the support pins, is inexpensive and in which the pin housing holes have a good abrasion resistance.
