Abstract
A web slitting and winding apparatus having at least a pair of vertical, parallel, plate-like slitter modules slidably movable laterally relative to one another for varying the distance therebetween. Each slitter module further has a pair of flanges extending toward one another for supporting a pair of coacting knives. A web is slit by the knives into a plurality of web strips which are guided and wound onto cores.
Claims18
A variable-width web slitting and winding apparatus comprising:
- a longitudinally extending bed;
- at least a pair of longitudinally spaced, parallel, and unitary plate-like slitter modules extending upwardly from and slidably mounted on said bed relative to one another, each slitter module having a pair of rigid flanges extending inwardly toward one another in parallel spaced relation;
- knife means rotatably mounted on each pair of said flanges of each slitter module for slitting a web fed through said knife means;
- means coupled to said slitter modules for slidably adjusting said modules on said bed for varying the distance between said pair of slitter modules and knife means and hence the width of a first strip slit by said knife means;
- a drivable first unitary winding drum parallel to said bed and laterally offset from one side of said pair of slitter modules;
- first core supporting means on said slitter modules for rotatably supporting a first core and positioning the first core adjacent to said first drum;
- and
- first guiding means for guiding the first slit strip between the first core and said first drum and onto the first core whereby the first slit strip is wound by said first drum onto the first core.

A variable-width web slitting and winding apparatus comprising:
- a bed;
- at least a pair of spaced parallel, plate-like slitter modules laterally extending from and slidably mounted on said bed relative to one another, each slitter module comprising a pair of substantially L-shaped plates secured together to form a substantially U-shaped member having a pair of upwardly extending spaced legs, said legs having a pair of rigid flanges extending inwardly toward one another in parallel spaced relation;
- knife means rotatably mounted on each pair of said flanges for slitting a web fed through said knife means;
- means coupled to said slitter modules for slidably adjusting said modules on said bed for varying the distance between said knife means and hence the width of a first strip slit by said knife means;
- a drivable first unitary winding drum parallel to said bed and laterally offset from one side of said pair of slitter modules;
- first core supporting means on said slitter modules for rotatably supporting a first core and positioning the first core adjacent to said first drum;
- and
- first guiding means for guiding the first slit strip between the first core and said first drum and onto the first core whereby the first slit strip is wound by said first drum onto the first core.
