A weaving machine, more particularly a projectile weaving machine (100), has weft break clearing devices (1, 2) at the shed entrance and exit. These devices form units with grippers and, for example, a suction device for removing a broken weft (110) and are mounted for pivoting or displacing them with an actuator or manually out of range of the warps. The mobility of the devices (1, 2) allows the weaver unrestricted access, for example, when clearing a warp break in the selvedge area.

Apparatus for storing and mixing blood samples comprises separate storage and mixing discs for storing and mixing blood samples in containers. The discs are driven independently and are provided with complementary grooves. A loading device loads the containers into the storage disc where they are transported to a transfer device. The transfer device successively transfers the containers into an oppositely situated groove of the mixing disc. The mixing disc mixes the blood samples via rotation thereof, after which the containers are transferred to a blood removal device which rotates each container with its blood sample about the lengthwise axis thereof so that a bar code reading device can read a bar code applied to the container. Blood is then withdrawn from the container and delivered to a blood analyzer, after which the container is ejected from the mixing disc by rotation of the mixing disc.

The filler wire is a closed tube, in whose interior is located a filling of two or more pulverulent material components. With the split tube still open, the filling is introduced in the form of layers and then the split tube is closed. As a result of the filling introduced in layer form, a favorable set of conditions for closing or sealing the tube, for example by welding, is provided.

Filler wire

In the installation, a strip is shaped from a split tube which is welded or seamed to give a closed tube in a welding or seaming station. Associated with the welding or seaming station is a suction mechanism used for the removal of on the one hand the cold air flow produced by the moving open tube and on the other the air flow heated during welding and flowing back from the closed tube, as a result of the reduction of the internal cross-section thereof. This obviates air turbulence in the welding or seaming station, which could whirl up the pulverulent material introduced into the open tube in a dosing station and could be deposited on the longitudinal edges of the split tube. This could unfavorably influence the seaming or welding process.
