Patented Sept; l, 193i -UNITED sTTEs PATENT. OFFICE CHARLES C. 'VAN STRY, 0F WEST ENGLEWOOD, NEW JERSEY, ASSIGNOR TO CAMERON MACHINE COMPANY, OF BROOKLYN, NEW YORK,
A CORPORATION OF NEW YORK SLITTING MEANS Application led April 5, 1930. Serial N0. 441,755.
This invention relates generally to slitting devices, and has for its main object and feature the production of a score-cut slitting device that will act not only as a slitting means but also as a separating device.
In the accompanying drawings the invention is disclosed in several concrete and preerred forms in which:
Fig. 1 is a vertical sectional view of a slitting device embodyingone form of the invention;
Fig. 2 is a detail sectional view substantialy on the plane of line. 2-,2 of Fig. 1; an
Fig. 3 is a View similarl to Fig. l-showing a modiiiedform of the invention.
Y1 indicates a backing member preferably having a glass-hard surface and 2 is a' score-cut slitter to coact therewith to sever web of flexible material 3. When slitting webs of flexible material of a certain character by the score-cut process, it sometimes occurs that 'there remainn a ewunsevered threads between the slitted sections, and it has been the practice heretofore to employ a stationary blade that projects between the slitted sections to cut any remaining unsevered threads. It will be understood that such blades must need be adjusted very carefully to be in exact alinement with the line of slitting as otherwise adjacent slitted sections may become distorted out of the lane of severance to such an extent thats'aid) sections may overlap or be otherwise adversely affected. To avoid these diiiiculties, and to simplify construction, the expedient indicated in Fig. 1 is resorted to As there shown, guiding means are provided to so lead the webof flexible material away from the slitting members as to cause said web to continue in engagement with the score-cut member after said web leaves vthe backing member, to thereby cause lsaid score-cut member to act as a separatingmember as well as a slitting member. Or to state the proposition differently, the slitting and guiding means are so arranged with respect to each other .that the score-cut and'backing members iirst coact on the lweband thereafter the scorecut memberalone acts on the web while the material including: av
latter is traveling'as Aan unsupported layer. In other words: the guiding means deiects the web of material, as it leaves the oint of enga ement of the score-cut and acking mem ers, into a path' inside the outer periphery of the score-cut slitting member. viously, said guiding means may take many forms. In Fig. 1 the guiding means are indicat'ed at 4, said guiding means being in thisinstance the front winding drum of a surface-winding machine.' It is to be under.- stood, however, that the invention is not to be limited to use in a winding machine but maybe utilized -as an independent slitting means, or as a. slitting means in other machines, such as printing machines, when no winding occurs.
In Fig. 73, backing member 5 is the front winding drum of a surface winding machine, and 6 indicates the scorecut slitting member coacting therewith. In this instance, web 7 vis led over roller 8 and in between the slitting members. 9 indicates a guiding roller that deflects the web in the manner previously indicated and which then leads said web to the upper surface of the front winding drum. yPreferably said roller 9 is mounted in twov arms shaft 11 so that the extent to which slitter 6 penetrates between the slitted sections of the web is variable.
1. Slitting means to sever a web of lexlble material including: a backingmember., a score-cut slitting member to coact therewith, and guiding means to so lead the web of flexible material away from the slitting member as to cause said web to continue in engagement with the score-cut member after said web leaves the backing member to thereby cause said score-cut member to act as a separatin member as well asa slitting member.
2. litting means to sever a web of iiexible backing member, a score-cut slittingmember to coact therewith, and guiding means to deiiect the web of ilexlble material, as it leaves the point of engagement of the score-cut and backing members?,
` into'a path inside theA outer periphery of score-cut slitting member.
10 that are adjustable about se ,4 3. Slitting means to sever a webV of fleximaterial, as itleaves the point of engagement of the score-cut and backin members, into a path inside the outer peripef-y of the scorecut slitting member, and means to adjust the position of theguiding means to thereinr Y 0 vary therlextent to which the slitting member penetrates between the slitted sections of the web. n Y Y Y Signed at the city of New York, inthe borough of Brooklyn,r county of Kings and State of New York, this 1l day of January, 1930.
