## Abstract

An apparatus is described for laying down continuous material 15, for example filament tows, which runs on a determined level, from which level it is given a meander form by means of a turning wheel 1, the periphery of which is provided with reversing elements 2. Forming of meanders from the continuous material 15 is performed by means of one single wheel 1. Catching devices 5 are provided between the reversing elements 2 which, from the outside of the plane of running continuous material 15, slue into this plane and by this inward motion form meanders of the running continuous material 15, and subsequently slue back from the plane of the continuous material 15 to their initial position, thus releasing the meanders of continuous material 15 formed for being laid down. The catching devices 5 can be arranged on forks 4 which slide in guide grooves 3 in the wheel 1, and the forks 4 can be driven by slide rods 10, whose motion cycle is determined by a cam disk 13.

## Claims

### Claim 1

An apparatus for forming meanders in a continuous spinning tow running in a plane comprising a single rotating wheel and meander-forming and -releasing means comprising:
reversing elements (2) arranged generally in a circle on the surface and around the periphery of the wheel (1) and, between each pair of reversing elements (2), a guide groove (3) in wheeel (1) for guiding a catching device (5);
movable catching devices (5), each catching device (5) arranged on a fork (4) sliding in a guide groove (3), and mechanical actuating means for the catching devices (5), each catching device (5) having an initial position, outside of the plane in which the continuous spinning tow is running and in closely spaced relation to the periphery of the wheel, and being movable from this initial position radially inwardly toward the axis of the wheel and into said plane; each fork (4) being fastened to the wheel (1) via a first joint (6), a connecting rod (7), and a pillow block (8);
said mechanical actuating means including means for:
sequentially moving the catching devices (5) to a relatively radially inward position from their initial position while also moving the catching devices into the plane in which the spinning tow is running thereby catching the spinning tow and forming a first meander of a sequential series of meanders in said spinning tow, each meander extending from a reversing element (2) to a catching device (5) which is in the relatively radially inward position, and
moving each catching device (5) back toward its initial position after the catching device has rotated more than 60.degree. of the circumference of the wheel (1), thereby releasing the meander;
the actuating means for each catching device (5) including a slide rod (10) for driving each fork (4) via a second joint (11); the slide rod (10) sliding in a corresponding track (14), and the motion cycle of the slide rod (10) being determined by a cam disk (13) via a cam roller (12).
