A working apparatus for pasting two continuous paper webs together having patterns is provided which can be made small as a whole and whose pasting processing treatment reduces a paper loss occurring when the apparatus starts to operate.To this end, the apparatus which has an upper paper line 1 along which a continuous upper paper web 2 having a pattern printed thereon is driven to travel by a drive unit, a lower paper line 3 along which a continuous lower paper 4 web having a pattern printed thereon is driven to travel by a drive unit, a pasting unit 5 for pasting the upper and lower paper webs together into a combined paper web 7 while registering the patterns on them with each other, a combined paper line 6 along which the combined paper web 7 is driven to travel by a drive unit and a processing unit disposed in each corresponding one of the lines upstream and downstream of the pasting unit for processing the paper web traveling along the corresponding line, comprises: a paste applying unit 23 disposed in the lower paper line upstream of the pasting unit and whose paste applying operation can be turned on and off; an upper paper winding unit 31 disposed downstream of the pasting unit for winding up the upper paper web passed through the pasting unit; and a drive source provided for each corresponding one of the drive and processing units and operable individually.
