The guide blades 71 and 72 receive the end pieces 15, which are partly interrupted as at 136. After having ap plied the glue portions the paper strip ‘11212 is united with the strip of bast »1-24. 'For this purpose, the strip of bast is guided over the guide rod .149 provided with the ad justable lateral guide rings 141 and 142. Due to these guide rings, the strip of bast is united with the paper strip as at 139 exactly in the central portion of the latter 16 of the handles and bring the same into the necessary position when the strip is transferred from the cylinder 58 to the cylinder 73. The central portion 14 of the handle is gripped by the grippers 74 and the end portions 15, 16 are ?rmly held against the cylinder by the suction nozzles 75. After having rotated with the ?rst cylinder 58 and having been transferred to the second cylinder 73, the handle has been turned due to this transfer to the cylinder bearing the central longitudinal uninterrupted strip of glue. 10. The united web, composed of the paper strip and the bast strip is then advanced to the cutting means 143 comprising the ?xed knife 144 and the two rotating knives 146 and 147, mounted on the rotary body 145. 73 rotating oppositely to the rotation of cylinder 58.
