A method and system for filling and for sealing valve bags of the type having a water activated sealing means on the interior of the filling valve. A fill spout or nozzle is provided to maintain the filling valve free from contamination by the material being dispensed into the bag. The nozzle has an air conduit that supplies air to a location adjacent the water activated sealing means during the filling operation and a water spray conduit that supplies a water spray to activate the sealing means at completion of the filling operation. A suction source is connected to the material supply passage of the nozzle and is actuated momentarily while the nozzle is being removed from the filling valve and prior to the end of the filling valve entering the water activated region of the valve in order to prevent material from falling from the end of the nozzle onto the activated portion of the sealing means. A sealing nozzle separate from the filling nozzle is also disclosed.

A machine for forming beveled webs, particularly for use in truss structures, includes a feed table upon which a wooden board is placed. A saw is shifted into cutting relation with the board to sever a web which drops into a hopper. A pusher displaces the web from the hopper and along a guide surface and eventually forms a row of webs which is pushed toward a beveling station. At the beveling station, a pair of cutters are situated at opposite sides of the guide surface and each include co-axially arranged router heads. The router heads are of frusto-conical configuration and form a cutting angle through which the webs pass. Top and bottom bevels are cut in the ends of the web by the router heads. The vertex of each cutting angle is spaced from the respective web end to form a flat on the web between the top and bottom bevels. The cutters are mounted for rotary adjustment to vary the inclinations of the router heads, and thus of the bevels being formed. The axis of adjustment lies on a plane bisecting the cutting angle so that the top and bottom bevels will continue to converge toward the center plane of the web.

A method and apparatus for severing a length of shirred casing from a length of unshirred casing utilizes a mandrel onto which an unshirred casing is introduced. A fluid is injected between the casing and the mandrel. The casing is shirred into tight overlays to provide a length of shirred casing. This length of shirred casing and the yet unshirred casing are engaged to displace them relative to and sever them from each other. Prior to severence, the casing is circumferentially weakened by thermal partial decomposition of the casing or by at least partial penetration with a weakening tool that does not engage the mandrel.
