Abstract: A mold for use in molding paint brush heads comprises a pair of mold forming assemblies adapted to form a mold cavity therebetween. Each of the assemblies comprises an upper segment and a lower segment which are adapted to be retained in an end to end relationship, the lower segment having a length through which a bristle knot can be inserted with ease. A molding machine for use in molding ferruleless paint brush heads is also disclosed in which there is provided the improvement of a mold assembly comprising a first pair of molding belts, each having oppositely disposed forward run portions extending continuously through a bristle loading station and then through at least one molding station. The forward run portions of the first molding belts have dividers extending therebetween which form plurality of mold cavities proportioned to receive the proximal end of a bristle knot therebetween. A second pair of molding belts each having a forward run portion are also provided. The forward run portions of the second pair of molding belts being disposed opposite one another and extending through said molding station in an edge to edge relationship, one with each first molding belt to extend the molding cavity to the full height of the required brush head.

Abstract translation: 用于成型油漆刷头的模具包括一对适于在其间形成模腔的模具成形组件。 每个组件包括适于以端对端关系保持的上部段和下部段，下部段具有长度，通过该长度可以容易地插入刷毛结。 还公开了一种用于成型无套圈涂料刷头的成型机，其中提供了一种模具组件的改进，该模具组件包括第一对成型带，每个成型带具有相对设置的向前延伸部分，其连续延伸穿过刷毛装载站，然后通过 至少一个成型台。 第一成型带的前进部分具有在其间延伸的分隔件，其形成多个模腔以成形以接收其间的刷毛结的近端。 还提供了具有前进部分的第二对成型带。 第二对成型带的前进部分彼此相对设置并且沿着边缘到边缘的关系延伸穿过所述成型台，每个第一成型带将模制腔延伸到所需刷头的整个高度。
