Abstract
A method of manufacturing a file folder includes the steps of displacing a predetermined length of a flexible material in a feed direction and forming a pair of spaced apertures in the material. The method further includes the steps of inserting a prong of a binder through each aperture, the binder having an elongate central portion with a prong extending from each end of the central portion and securing the central portion of the binder to the material. The invention also relates to an apparatus for manufacturing a file folder.
Claims19
An apparatus for manufacturing a file folder, the apparatus comprising:
- a displacement means for displacing a predetermined length of a flexible material lengthwise in a feed direction, said flexible material having a first side and a second side;
- an aperture forming means for forming a pair of spaced apertures in the material, the aperture forming means being a punching device which includes a punching die which is displaceable towards and away from the material to punch the apertures in the material, with the punching die being configured so that when the punching die executes an operating stroke, at least a region between the apertures is embossed to define a depression;
- an inserting means for inserting a prong of a binder through each aperture from the first side of the material, the binder having an elongate central portion with a prong extending from each end of the central portion;
- and
- a securing means for securing the central portion of the binder to the first side of the material.

- a supply means for supplying the flexible material from a roll of the flexible material;
- and
- a parting means for parting the material to form sheets, so that each sheet has the predetermined length.
