Abstract

A device for providing a material band, including: an unwinding device for unwinding a material band, having two holders for receiving a respective roll of the material band, both holders being movable from a non-working position, in which a roll is received, and a working position, in which the roll is unwound; a transport device, downstream of the unwinding device, for the unwound material strip; a device for connecting a rear end of the unwound material band to a front end of the material band to be unwound; a position detection device including a sensor device for detecting sensor information which describes the position of the strip material in the holders, and a control device for detecting position information based on the sensor information. The position of the strip material to be unwound relative to the unwound strip material can be aligned as a function of the position information. The sensor information can be detected by the sensor device during the movement of the holders from the non-working position into the working position and the control device determines the position information and controls an actuator for moving the respective holder transversely to the transport direction of the transport device as a function of the position information so that the respective holder is positioned at the end of the movement into the working position so that the end of the material band to be unwound is aligned with the end of the un-wound material band.

Dependent claims

A device for providing a material band, in particular a cord band, comprising:

an unwinding device for unwinding a material band received in the form of a
roll, comprising a first and a separate second holder for receiving a respective roll of the material band, wherein the first and the second holder are each reversibly movable from a non-working position, in which a roll is received or prepared, and a working position, in which the roll is unwound,
a transport device downstream of the unwinding device for picking up the unwound material band,
a device for connecting a rear end of the unwound material band located on the transport device to a front end of the material band to be unwound,
a position detection device comprising a sensor device for detecting sensor information which describes the position of the band material to be unwound in the first and second holders, and a control device for detecting position information on the basis of the sensor information, wherein the position of the material band to be unwound can be aligned relative to the unwound material band as a function of the position information,
wherein the sensor information can be detected by means of the sensor device during the movement of the first and second holders from the non-working position into the working position and the control device is set up to determine the position information and to control actuating means for moving the first and second holders transversely to the transport direction of the transport device as a function of the position information in such a way, that the first and second holders are positioned at the end of the movement into the working position in such a way that the end of the material band to be unwound is aligned with the end of the unwound material band.
