Verfahren und Vorrichtung zur Herstellung von Borstenwaren aus Kunststoff

摘要

Brushwear can be manufactured by melting the bristle bearer and, if appropriate, the ends of the bristles and joining them together under pressure or by inserting the bristles into an injection or foam mould for the bristle bearer and embedding them in the bristle bearer material by injection or foaming. Due to the thermal processes (heating, melting, injecting, cooling), the cycle time for these processes is very long. It can be reduced considerably by moving the tools for holding or manufacturing the bristle bearer on the one hand and clamping devices for the bristles on the other hand on closed-loop paths, transferring the clamping devices to at least one common station on the path of the tools, moving them along with the tools at least during the thermal processes and then returning them to their path of movement.
