W. E. MQLINS MECHANISM FOR SEVERING MOVING WEBS INTO LENGTHS Filed Jan.22, 1927 Patented Nov. 29, 1927.
UNITED STATES PATENT OFFICE.-
MECHANISM FOR SEVERING MOVING WEBSv INTO LENGTHS.
Application filed January 22, 1927, Serial No. 162,910, and in Great Britain January 22, 1926.
This invention is for improvements in or relating to a device for severmg a moving web 1nto lengths and more partlcularly to a device wherein the cutting mechanism com-' prises a fixed blade adapted to co-operate .with a rotary blade, and it is the object of the present invention to provide on such a device means whereby the leading edge of the sever-ed web is simultaneously deflected from both the fixed and rotary blades in its path through the machine.
The present invention consists of a device for severing a travelling web of paper or the like, into lengths which comprises in combination a fixed cutting blade a rotary cutting blade, means adapted to deflect the leading edge of the freshly cut web out of the path of the fixed blade and an air current adapted to deflect the leading edge of the web out of the path of the rotary blade.
The invention is more particularly described with reference to the accompanying drawing which illustrates one method of carrying the invention into effect wherein gig. 1 is a section of the cutting device, an
' Fig. 2 shows the parts in a different position.
Referring to the drawing which illustrates a cuttin to Britis patent specification No. 245,261, wherein a resilient deflector 1 isarranged to operate in conjunction with the fixed blade 2 in the manner described in British patent specification No. 245.261 to remove the lead ing edge of the freshly cut web out of the path of the fixed blade 2. It is found in practice that when the leading edge of the web has been deflected from the fixed blade there is a tendency for the same to be attracted by the rotary blade 3 and adhere to the same, thereby rendering the delivery of the various strips to a stacking mechanism extremely difficult.
In the deflebtor described in my British patent specification No. 245,261, the deflector is mounted so as to be directed towards the cutting edge of the fixed blade 2 in such a manner that the free end of the deflector 1 is located in the .path of the rotary blade.
According to one construction of the presmechanism constructed according ent invention the deflector associated with the rotary cutting blade comprises a pneumatic device 4 adapted to produce an upwardly directed air blast indicated by the numeral 5 and adapted to issue from the nozzle 6 of the device 4 in a line joining the nozzle 6 with the free end of the deflector 1.
It is found in practice that as the web is being fed through the machine the air blast 5 associated with the rotary blade 3 is deflected by the surface 7 of the rotary cutting blade on to the travelling web 8 and the inclmation of the air blast varies as the rotary cutting blade moves towards the fixed blade. After the Web has been severed the air blast supports the leading edge of the web and peels 1t from the edge of the rotary blade.
The force of the air blast is suflicient to destroy any tendency for the Web to adhere to the rotary blade, and also acts as a support which, in the case of a freshly printed surface, prevents any tendency to smear.
In addition to the oblique blast there may i be provided air nozzles 9 and 10 on either side of the cutting mechanism which permitan upwardly directed blast of air to support the web in its forward movement, and there- 'after support the strips in their path towards the stacking mechanism so as to ensure that the printed strip does not come in contact with any surface which might smudge the same.
What I claim as m invention and desire to secure by Letters atent is 1. A device for severing a travelling web of paper or the like into lengths, which comprises in combination a fixed cutting blade,
a rotary cutting blade, means adapted to deflect the leading edge of the freshly cut web out of a path which includes the fixed blade and an air current adapted to deflect the leading edge of the web out of the path of the rotary blade.
2. A device for severing a travelling web of paper or the like into lengths which comprises in combination a fixed cutting blade, a rotary cutting blade, a resilient deflector 1nclined to the plane of the fixed blade in such a manner that the leading edge thereof is located in close proximity to the edge of the fixed blade and in the path of the rotary blade in such a manner as to deflect the leading edge of the freshly cut Web out of a path which includes the fixed blade and an air current adapted to issue in the direction of movement of the rotary blade, but directed away from the axis of the rotary blade and towards the free end of the deflector of away from the edge of the rotary blade.
In testimony whereof I hereunto affix my slgnature.
WALTER EVERETT MOLINS.
