A method and a cutting device for the continuous cutting of fibers fed in fiber cables into fiber sections of particularly short length is disclosed. In order to avoid high friction forces between the formed knives and the fiber sections, and furthermore, to prevent excessive deforming of the fiber section during the transport between the knives, the knives are arranged at an offset to each other such that the fibers are initially cut into longer fiber sections, and into shorter fiber sections in a second step. The respective free space between the knives is increased due to the offset arrangement of the knives.

Method and device for the continuous cutting of fibers

The invention relates to a device and method for melt spinning and cooling a filament bundle. To this end, the device comprises a spinning device with an annular spinneret for extruding the filament bundle as well as a cooling unit arranged below the spinning device. The cooling unit comprises a holding device and a coolant dispersing head that is connected to said holding device. In an operating position, said coolant dispersing head is substantially centered relative to the spinneret with contact between the spinning device and the holding device. The coolant dispersing head can be guided into a standby position at a distance from the spinneret. According to the invention, a movable shielding means is arranged laterally of the coolant dispersing head and can be moved between an initial position laterally of the coolant dispersing head and a shielding position directly underneath the spinneret.

A device for cutting a fiber cable, in which a rotationally driven cutter supporting member and a rotatable pressing ring positioned at an incline relative to the cutter supporting member work together to cut the fiber cable. An annular channel formed on the outer circumference of the cutter supporting member is penetrated by a plurality of radially oriented cutting blades. The cutting blades are held in a cutter receiving member of a holding device, wherein a supporting ring radially supports the cutting blades. The width of the cutting blades is larger than the width of the annular channel. In order to consecutively use several areas of the cutting blades, the supporting ring is replaceable and is formed by an outer ring encircling the cutting blades or by an inner ring encircling the cutting blades. The cutting blades are held in the cutter receiving member and are radially moveable.

An arrangement for stretching thermoplastic fibers of synthetic polymers, particularly polypropylene, polyester or polyamide, for producing high strength yarns, comprises a delivery mechanism for delivering fibers, a stretching mechanism for stretching fibers, and a plurality of heated rollers arranged between the delivery mechanism and the stretching mechanism for deviating the fibers and means for applying to the fibers a force which is opposite to a direction of movement of the fibers, none of the rollers being driven and at least one of said rollers is provided with a brake, the fibers passing around the rollers without slippage.

An apparatus is disclosed by which ropes and similar elongated objects can be accumulated in storage cans. The object is advanced through an upright stationary upstream guide tube and through a rotating downstream guide tube and its discharging end distant from the axis of rotation. A braking drum coaxially surrounds the orbiting trajectory of the discharging end of the downstream guide tube so that the portions of the objects which are being discharged through the discharging end impinge against the inner surface of the braking drum. The inner surface of the braking drum is arched, such as partly circular or partly parabolical in axial section and the objects rebound therefrom at an angle corresponding to the angle of incidence of the object on the inner surface. The downstream guide tube has a cross section exceeding that of the upstream guide tube. A ceramic annular element is arranged at the lower end of the upstream guide tube. The downstream guide tube is welded in a rotary body and the discharging end thereof is flush with the outer periphery of the rotary body. The upstream guide tube is accommodated in a hollow shaft of the motor which directly drives the rotary body.
