Abstract
Method and apparatus for determining the width and location of stored rolls of receiving material in web form, in which an unrolled initial strip of an inserted roll is fed past a measuring device disposed along a transport path provided jointly for receiving material fed from the rolls. The measuring device determines the width of a roll of web material when its initial strip is cut off by a cutting device, and the measured value together with a data item representative of the storage location of that roll being stored in a memory.
Claims7
A method for automatically and selectively supplying material in web form of different widths from one of a plurality of storage locations in a common path, comprising:
- (a) feeding a part of the stored material web into said common path;
- (b) measuring the width of said part and generating a signal representative of the storage location from which said part originates;
- (c) determining a data item representative of the measured width and the signalled storage location;
- and
- (d) removing from said common path the supplied part of the material web.
In apparatus comprising a holder for a plurality of rolls of web material of different widths, said holder having different locations into which said rolls can be inserted, transport means for selectively supplying web material from a roll located at holder location into a first common transport path, and a memory for storing data representative of the width and location of each roll in the holder and data inputting means for inputting said data into the memory, the improvement in combination therewith comprising a measuring device for measuring the width of the web material at a location situated in the first common transport path for providing a measurement signal representative of said measured width, and means for generating a second signal representative of the location of a roll from which the associated web material originates, said data inputting means in response to said measurement signal and the second signal automatically storing in said memory a data item representative of the width of the roll of web material at its location in said holder.
