Strip continuous supply method and apparatus

Abstract

In a feeding apparatus which includes a turret arm supporting a new paper roll and an old paper roll and supported pivotably, and a turret arm swing motor for pivoting the turret arm, and which splices a web of the new paper roll to a web of the old paper roll and supplies the web continuously, the turret arm swing motor is driven before driving of a main unit to pivot the turret arm, thereby moving the new paper roll to a web splicing standby position.

1 . A strip continuous supply method of a strip continuous supply apparatus which includes a turret arm supporting a new web roll and an old web roll and supported pivotably, and a turret arm drive device for pivoting the turret arm, and which splices a strip of the new web roll to a strip of the old web roll and supplies the strip continuously, 
 the strip continuous supply method comprising:    driving the turret arm drive device, before driving of a main unit, to pivot the turret arm, thereby moving the new web roll to a web splicing standby position.    
   
   
       2 . The strip continuous supply method according to  claim 1 , further comprising: 
 moving a web splicing unit to the web splicing standby position before driving of the main unit,    wherein the web splicing unit includes a pressing member for pressing the strip of the new web roll against the strip of the old web roll, and a cutting member for cutting the strip of the old web roll.    
   
   
       3 . The strip continuous supply method according to  claim 1 , further comprising: 
 driving new web roll drive means such that a peripheral speed of the new web roll becomes equal to a transport speed of the strip unwound from the old web roll, when the main unit begins to rotate,    wherein the new web roll drive means is adapted to rotate the new web roll.    
   
   
       4 . The strip continuous supply method according to  claim 2  or  3 , wherein 
 when a rotational speed of the main unit is equal to or higher than a preset rotational speed, the new web roll is moved to the web splicing standby position, and the web splicing unit is moved to the web splicing standby position, and    the new web roll drive means is driven such that the peripheral speed of the new web roll becomes equal to a transport speed of the strip unwound from the old web roll.    
   
   
       5 . A strip continuous supply apparatus, comprising: 
 a turret arm supporting a new web roll and an old web roll and supported pivotably;    a turret arm drive device for pivoting the turret arm, and which splices a strip of the new web roll to a strip of the old web roll and supplies the strip continuously; and    a control device for driving the turret arm drive device, before driving of a main unit, to pivot the turret arm, thereby moving the new web roll to a web splicing standby position.    
   
   
       6 . The strip continuous supply apparatus according to  claim 5 , further comprising: 
 a web splicing unit including a pressing member for pressing the strip of the new web roll against the strip of the old web roll; and    a cutting member for cutting the strip of the old web roll,    wherein the control device moves the web splicing unit to the web splicing standby position before driving of the main unit.    
   
   
       7 . The strip continuous supply apparatus according to  claim 5 , further comprising: 
 new web roll drive means for rotating the new web roll,    wherein the control device drives the new web roll drive means such that a peripheral speed of the new web roll becomes equal to a transport speed of the strip unwound from the old web roll, when the main unit begins to rotate.    
   
   
       8 . The strip continuous supply apparatus according to  claim 6  or  7 , wherein 
 when a rotational speed of the main unit is equal to or higher than a preset rotational speed, the control device moves the new web roll to the web splicing standby position, and also moves the web splicing unit to the web splicing standby position, and further drives the new web roll drive means such that the peripheral speed of the new web roll becomes equal to the transport speed of the strip unwound from the old web roll.
