Definitions
- the invention relates to a method and a device for the lateral alignment of an edge edge of flat material webs fed to a processing station, the lateral position of the edge edge being measured by measurement technology transversely to form a position signal, and the flat material web being measured transversely in accordance with the position signal is transported to the feed direction.
- the solution according to the invention is based on the idea that two elongated cylindrical friction rollers with axes of rotation oriented transversely to the feed direction can preferably be used for the transverse transport, with soft-elastic surfaces which are alternately pressed against the flat material web during operation and with the entrainment of the entrainment Push the flat material web back and forth in the direction of its axis of rotation in accordance with the position signal between two end positions and on the other hand lift it off the flat material web, the roll change being triggered each time one of the end positions is reached.
- These measures have the advantage that the friction rollers rest against the flat material web over a greater width without gaps, so that no undesired notches or distortions can occur in the flat material surface during transverse transport.
- a further improvement in this regard is achieved in that the friction rollers have a Have surface layer made of elastomeric, preferably rubber ⁇ elastic material.
- transverse transport is stopped during the roll change, which can be carried out very quickly with suitable drive means. This is particularly important if, during the roll change, both friction rolls are temporarily pressed against the surface of the flat material. After a roll change, the transverse transport with the replaced friction roll can initially be continued in the same direction as before the roll change.
- the transverse transport in the direction of the end positions is advantageously slowed down by suitable drive means, so that only slight acceleration forces occur when the transverse transport is stopped and when the vehicle is started again.
- the respectively active friction roller is pressed against the flat material web under the action of a preferably adjustable spring force.
- a particularly advantageous embodiment of the invention which can be implemented with simple means, provides that the two friction rollers are moved in opposite directions, both in the case of transverse transport and when changing the rollers.
- both friction rollers are expediently brought into a preselected basic position, for example into a middle sliding position between the end positions.
- one of the two friction rollers will be aligned against the de Flat material web brought to the plant.
- the device for carrying out the method according to the invention which has a sensor arrangement for detecting the lateral position of the marginal edge transversely to the feed direction and a transverse transport device which responds to a position signal which can be tapped at the output of the sensor arrangement and which acts on the flat material web, contains two their axes, which are oriented transversely to the feed direction, can be rotated cylindrical friction rollers, one of which alternately abuts a friction roller against the flat material web and can be pushed back and forth between two end positions in the direction of its axis of rotation according to the position signal, and the other friction roller can be moved by the mate ⁇ , taking the flat material web with it Rialbahn is lifted, the role change can be triggered by an end position signal generated when reaching an end position.
- a preferred embodiment of the device according to the invention provides that the transverse transport device has an interchangeable mechanism which responds to the end position signals, moves the friction rollers alternately against the flat material web and lifts it off, and has two end position switches, preferably designed as proximity switches, for emitting the end position signals.
- the two friction rollers are advantageously pushed back and forth in opposite directions in the direction of their axes of rotation. arranged in bar.

- the cross slide are advantageously driven in opposite directions by a common stepper motor and an eccentric gear.
- the eccentric gear can each have a roller bearing designed as an eccentric and engaging in the guide window of the cross slide and / or the change slide.
- the shuttle valves are expediently driven in opposite directions by a common, preferably pneumatic, rotary motor and an eccentric gear against the force of a spring force acting in the direction of the flat material web. It is thereby achieved that the friction rollers are pressed against the flat material web which can be displaced on a support under the action of the spring force when the eccentric gear on the shuttle slide side is disengaged.
- the eccentric gear on the changer slide side each has an idle angle starting from the pressing position of the associated friction roll, which ensures that the roll against the fabric web when changing the roll under the action of the spring force, the friction roller resting against the flat material web is lifted only after a dead time has elapsed, after the other friction roller is already resting against the flat material web.
- the processing station is advantageously designed as a sewing head of an automatic sewing machine and the flat material web is designed as a fabric web.
- other areas of application of the invention are also conceivable, for example in the supply of paper webs, plastic webs, sheet metal webs to suitable processing stations.
