Before they are fixed as by the adhesive, the strip II is maintained steady under fixed even tension to prevent displacement of the blades while they lie free thereon and. It will’be understood that, due to the reliability of thelrotary motions utilized in my increased machine, the cutting blades are organised by sticky at their ,4 recessed corners with no sticky getting upon the cutting blades. A transverse blade 33 then severs the patient covered .rotor blades, as shown at 40 Fig. 3, and’iust as each packaged blade 29 is severed it really is seized by a set of moves 4| powered at a bit elevated rate and which consequently have a tendency to rip the severed wrapped blade through the succeeding blade, insuring a good severance, and provide it to your stack: or even the packaged cutting blades could be provided instantly to a tucking machine for installation in lots inside the usual cardboard pack or tuck, and thence to the final cover, like Cellophane.
