Method and apparatus for supplying material in web form

Claim 3

A method according to claim 1, wherein said removal is effected by withdrawing said material web from the common path.

Claim 4

A method according to claim 1, wherein the removal is effected by cutting off that part of the web material which is located in said common path and discharging the part so cut-off.

Claim 5

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.

Claim 6

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.

Claim 7

The improvement according to claim 4, including (a) a cutting device disposed in said common transport path in front of the measuring station for cutting an initial strip from a roll of web material inserted in said holder and (b) means for activating said data inputting means upon activation of the cutting device after insertion of said roll.

Claim 8

The improvement according to claim 5, including a deflecting element disposed after said cutting device for deflecting web material originating from a roll of said web material in said holder into a second common transport path and wherein said measuring station is positioned in said second transport path.

Claim 9

A copying machine for copying an original on receiving material, which copying machine is provided with adjustable margining means for limiting the area in which copying is carried out in a direction transversely of the feed direction of the receiving material, and having apparatus according to claim 4 in which said receiving material in web form can be fed from a selected roll and separate sheets of receiving material can be fed via said second transport path into said copying machine; margin adjusting means adapted to adjust said margining means in accordance with the data item stored in said memory as representative of the width of the selected roll of web material when the copying machine is set to copy on receiving material in web form; and which, when the copying machine is set to copying on separate sheets of receiving material, in response to an incoming sheet activate the measuring device and the margining means for automatically setting the margining means in accordance with the measured width of the sheet.
