A filament-transportation device has a plurality of tube elements for transporting filaments from an intake area to an outtake area via an airstream generated by underpressure or overpressure. Each tube element has an end orifice. A baffle-plate unit has a baffle plate having a through-hole, a top surface opposite to the end orifices to stop the transport of the filaments, and a bottom surface opposite to the top surface. The baffle plate includes baffle plate elements associated with the end orifices. Each of the baffle-plate elements has a top surface forming part of the top surface of the baffle plate, a bottom surface forming part of the bottom surface of the baffle plate, and a side surface extending between the top and bottom surface. There is a plurality of bridge elements, each having a top surface forming part of the top surface of the baffle plate, a bottom surface forming part of the bottom surface of the baffle plate, and a side surface extending from the top surface of the bridge element to the bottom surface of the bridge element. The through-hole is defined either by the side surfaces of at least two baffle plate elements or by the side surfaces of at least one baffle plate element and of a side surface of at least one bridge element not facing an end orifice of a tube element, which bridge element connects two spaced apart baffle plate elements from the plurality of baffle plate elements.

Filament transportation device

A transportation device for transferring bristles from one location to another location comprises a tube system and a baffle plate comprising conically shaped vents. The baffle plate is arranged at one end of the tube system in order to stop the movement of the bristles transported inside the tube system using airflow. Such a transportation system may be part of a device for automated production of brushes, in particular toothbrushes. A plurality of bristles can be transferred by such transportation system in order to be arranged in a pre-defined bristle pattern corresponding to a bristle field of a brush, in particular a tooth brush.
