Abstract: An injection molding apparatus for injection molding articles from plastic, has a guide that extends along a plurality of stations, including at least one injection molding station, and along the guide at least one slide can be driven successively through the stations, wherein the or each slide transports the article to be produced from station to station. The slide or the plurality of slides altogether have associated therewith a plurality of motors which are seated on the slide or the slides. The motors have associated and moved therewith lines for supplying electrical power and/or at least one line for signalling, which are coupled with a stationary electrical power source or a stationary controller, respectively. At least one of the lines is guided from one motor to another. The motors are coupled with the at least one line in respect of the transfer of electrical power and/or signals.

Abstract: An injection molding tool is used to produce plastic parts such as toothbrush bodies or razor handles, for example. The tool has a stationary center mold block and a pair of outer mold blocks. The center mold block has two parallel opposed molding faces joined by two parallel opposed side faces extending perpendicular to the molding faces. The molding faces have parallel partial mold cavities formed therein and the outer mold blocks each are associated with one mold face of the center mold block and each have a molding face with parallel partial mold cavities formed therein which together with corresponding partial mold cavities of the associated mold face of the center mold block form complete mold cavities. Holders are indexed alongside the peripheral faces and around corners formed between the peripheral faces to hold and transport molded parts alongside the peripheral faces of the center mold block.

Abstract: A brush, in particular for household or industrial applications, has a bristle carrier plate made of plastic, a multitude of bristle bundles, which are attached in the bristle carrier plate, and at least one reinforcement plate, which is likewise made of plastic and is attached to the bristle carrier plate.

Abstract: A tuft picker device for a brush making machine has a bristle magazine for holding a supply of loose bristles and a tuft picker having a tuft picking notch being movable past an open side of the bristle magazine in a working stroke. A shield member is adapted to be shifted across the tuft picker notch to change the effective depth thereof. The shield member can be adjusted by an adjusting device in each working stroke in order to vary the effective depth of the tuft picking notch from one working stroke to the next to change the size of a tuft engaged in the notch.

Abstract: A bristle insert, in particular for a brush, is formed by at least one bristle pack having a plurality of plastic bristles whose ends are fused to each other to form a self-supporting holding element. A brush with such a bristle insert, and a method for manufacturing such a bristle insert is also provided.

Abstract: Method for manufacturing plungers for medical syringes, whereby such a plunger (3) consists of at least two parts, namely a longitudinal plunger body (4) made of plastic and a piston body (5) provided at the front end of the plunger body (4) which consists of a plastic which is softer than the plastic of the plunger body (4), characterised in that such a plunger (3), or at least a part (36) thereof, is formed by first manufacturing the piston body (5) and then the plunger body (4), or at least a part (37) of this plunger body (4), by means of injection moulding, whereby the plunger body (4), or the above-mentioned part (37) thereof, is injected against the piston body (5).
