Abstract: A blade sharpener which has two elements, one of which is a hand-held member, and the other of which is a follower member is disclosed. The two members are pivotally secured each to the other, and secured at variable preselected pivot points so that adjustments can be made for the particular skate, and for the particular cross-section of the blade desired at various points along the power toe section, neutral under foot section, and turning heel section. Means are provided interiorly of the two members to optionally secure a file or a neutral member such as a wooden dowel to the end that varying portions of the blade can be sharpened while moving the hand-held member back and forth longitudinal of the blade. Guide means are supplied on both members for securing the relationship of the file or abrading member to the blade in a preselected centralized orientation.

Abstract: A cut and score die apparatus is provided for progressively converting a sheet of material into blanks. The apparatus includes a punching section for punching scrap material from the sheet of material to define an array of interconnected blanks arranged in a grid of rows and columns on the sheet of material. A scoring section is provided for simultaneously scoring a first predetermined pattern on a trailing portion of a first row of blanks and a second predetermined pattern on the leading portion of a second, succeeding row of blanks on the sheet of material. A blanking section is also provided for piercing the sheet of material in a predetermined pattern to cut blanks from the sheet of material without producing any additional scrap material.

Abstract: A method for the manufacture of a hose package by folding a hose of flexible material, where the hose package consists of folds adjoining one another and forming wall elements connected to one another. The elements are situated outside one another in relation to a central axis of the hose package. The device for carrying out the method has a fixing element and upper and lower folding plates in the shape of polygons. Through a controlled sequence of movements, the fixing element and folding plates form the folds situated outside one another, and thereby the hose package. The folding plates are placed adjacent to one another and in end regions form corners of the polygon. In the respective corner regions the plates are spaced from one another to form an opening or gap through which a pressing member can travel to contact the folds of the hose package and smooth out any wrinkles.

Abstract: A pad sander paper punch assembly includes a base member having three upstanding walls for locating thereon a standard size sheet of sandpaper. A plate member is then placed over the sheet of sandpaper, the plate member having locating tabs which cooperate with the upstanding walls on the base member. The plate member and the base member are both perforated in locations corresponding to suction holes on the platen of the pad sander and a punch is then utilized to pass through the plate and base member perforations to appropriately perforate the sandpaper sandwiched therebetween. The base member is further formed with recessed walls so that the sandpaper may be creased at its ends to go over the sander platen with the perforations therein properly aligned with the suction holes in the sander platen.

Abstract: This disclosure provides an apparatus used in combination with an envelope feeder of the type having a frame with a generally horizontal feeder tray and a rack holding a stack of envelopes, the feeder having an endless belt supported on the feeder tray and the feeder serving to deliver envelopes from the stack onto the endless belt, the endless belt moving the envelopes to form a short-height stack at the outer end of the tray where the envelopes may be picked up by a printing press, a flap closure to close the envelope flaps so that open flaps do not interfere with the stacking process, the closure being in the form of an elongated member supported at the feeder tray outer end and having a first upper surface portion inclined upwardly in the direction away from the envelope feeder and a second horizontal upper surface spaced in a direction away from the envelope feeder, the second surface being in a plane parallel to and spaced above the plane of the endless belt.

Abstract: An apparatus and method for manufacturing reclosable thermoplastic containers which eliminates the need for spot-sealing zipper closures or zipper closure elements to a web of thermoplastic film prior to forming side seals and zipper end seals is provided. Opposing seal jaws provide increased heat and pressure to zipper closures in a manner which results in improved hermetic and fluid-tight side seals and zipper end seals.
