Abstract
An auto-splice device includes a cutting conveyer on which a sheet is cut to produce a fabric, a vacuum take-out unit for taking the fabric from the cutting conveyer onto a take-out conveyer, and a splice mechanism for splicing the fabric to another fabric on the take-out conveyer. A sheet end position measuring unit controls the location at which the fabric is held by the vacuum take-out unit.
Claims4
An auto-splice device comprising:
- a cutting section including a cutting conveyer, and cutting means for cutting a sheet on the cutting conveyor across the sheet to produce a fabric a take-out conveyor disposed downstream of said cutting conveyor;
- a vacuum conveyance means for conveying the fabric from said cutting conveyer onto said take-out conveyer;
- splice means for splicing the fabric to another piece of fabric on said take-out conveyer;
- and sheet end position measuring means for measuring the distance between a reference line and at least one side edge of the sheet during the cutting of the sheet with said cutting means and for controlling said vacuum means to catch and hold the fabric at a location determined based upon said distance.

A method of splicing pieces of fabric to one another, said method comprising:
- cutting a sheet, lying on a conveyor, thereacross to produce a first piece of fabric;
- while the sheet is being cut, measuring the distance between a reference line and at least one edge of the sheet which will form an end of the first piece of fabric;
- catching the first piece of fabric with suction from a vacuum conveyance unit at a location on the piece of fabric determined on the basis of said measuring;
- while the first piece of fabric is caught, moving the vacuum conveyance unit to overlap a front end of the first piece of fabric with a rear end of a second piece of fabric;
- and
- splicing the ends of the pieces of fabric together while the ends are overlapped.
