Translation of "Flying shear" in German

With the following flying shear the processings of the profile are terminated and the cut is executed too.

German Publication DE-OS 26 54 866 discloses a flying shear with blade drums rotationally connected with each other.

Then we have the passivation tunnel and the flying shear to cut to measure the product.

Besides the flying shear with ball recirculation movement allows high precision.

The disclosure involves an apparatus (1) for the flying-shear cutting of thin-layer material, reeled off from a coil, by laser radiation, especially metal strips, fabrics, synthetic resins, paper, cardboard, and composite materials.

The stacking table arms 49 will then lower by a partial stroke into position 49" to take the next double layer of bars 52. The stacking cycle is recommenced in accordance with FIG. 4a. In their spaced arrangement behind the flying shear 6, the partial groups of bars 50 and 51 will enter the feed roller table 11a at a speed of about 1.5 to 2 m/sec, which will allow the bars to come to rest relatively fast.

A continuous operation type flying shear 6 is located immediately downstream of the straightener 5 and may be moved back and forth in the direction of bar feed on a bed 7.

The invention relates to an apparatus for the flying-shear cutting of thin-layer material, reeled off from a coil, by laser radiation, especially metal strips, fabrics, synthetic resins, paper, cardboard, and composite materials.

An apparatus 1 for the flying-shear cutting of thin-layer material reeled off from a coil is arranged at a transverse and longitudinal cutting facility.

Flying shear: A special, repetitive motion profile is used when a continuous material flow must not be interrupted by cutting, printing, testing, or otherwise processing the material: While processing (e.g. cutting) the material the slave axis has to synchronize with the material flow, after that it has to run back to the starting position.

This equipment product line includes hydraulic decoiler, sheet leveling machine, servo feeder, multi-station punching machine, material storage looper device, Roll Forming Machine, flying shear with track, high-speed punch, cut for hydraulic systems and special PLC automatic electrical control systems.

This function, called "Flying shear" or "Flying saw", is already integrated in the digital servo drives by ESR (partly as an option) and requires only a small effort during parameterization (for cutting length, return velocity etc.).

Then we have the passivation tunnel and the flying shear with saw with fast disc to cut to measure the product.

They are also suited for safety applications and feature sophisticated functions such as synchronization, coordinated multi-axis operation, and flying shear.

In front of the device according to the invention, there are flying shears of standard design, which are not shown in more detail.

The Flying Shears are characterized by a robust construction to guarantee long lasting operation.

These Flying Shears are designed to fulfill the demand from Customers for cutting heavy-gauge high-strength steel.

BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a method of alternatingly operating one of several reels arranged following a continuous strip rolling mill, wherein the continuously arriving rolling stock is cut into coil weights of desired lots by means of flying shears provided at the exit of the rolling mill.

The continuously arriving rolling stock is divided by means of the flying shears into such lengths that, after the lots have been wound up, desired coil weights are obtained.

In accordance with the present invention, the above object is met by providing at least one driver following the flying shears, wherein the rolls of the driver can be displaced in such a way that the plane extending through the two axes of the rolls can be pivoted from an essentially vertical position such that a normal extending relative to this plane is pivoted in the direction toward the first of the following reels.

However, there are also facilities for the cutting of sheet metal wherein "flying shears" are employed permitting a cross-cutting of strip-shaped material without having to arrest the strip material.

In such flying shears, though, relatively large masses must be accelerated and decelerated so that high strip speeds are hardly possible.

Thanks to our experience, the design of these Flying Shears guarantees ease of access for a safe and easy maintenance.

To move from continuous operation into discontinuous operation of the rolling mill, the control and/or regulation unit 8 controls a separation device 7, for example flying shears, which is arranged between finishing rolling train 2 and casting device 6, preferably after a high reduction mill 11 and which continuously separates rolling stock G embodied between casting device 6 and finishing rolling train 2 .
