A slitter scorer having upper and lower web paths is provided with suction trim means along opposite edges of a web to be processed. Adjacent each suction trim means, and associated with each of said paths, there is provided a web deflecting means for flattening a web.

Automatic slitter scorer with web support

Web slitting apparatus is provided with a web guide below the web path. The web guide is moveable between operative and inoperative positions. In the inoperative position, the web guide has a portion for supporting a central portion of the web when it is desired to process a web as mill run board.

Web slitting apparatus

A frame supports an upper set of trim chutes movable toward and away from each other as well as a lower set of trim chutes movable toward and away from each other. The frame supports an upper web support member and a lower support member thereby defining two web paths. Each trim chute has a portion pivotable to an inoperative position wherein the extent to which each end portion projects in an upstream direction is decreased.

Trim chute apparatus

A corrugated paperboard slitter scorer has slitting and scoring heads movable individually or as a group along an expandable shaft by way of a master shifter. The expandable shaft provides a friction drag to maintain a head in position until all heads are simultaneously locked to the shaft.

Head locking means for slitter scorer

The tool positioner of a slitter scorer has tool engaging elements which are at least in part cylindrical and coaxial with a piston connected thereto. The cylindrical portion and piston are each independently guided by stationary guide surfaces in order to minimize bending forces on the piston.

Rotary tool positioner

An automatic slitter scorer apparatus is disclosed for slitting and scoring a corrugated paperboard web. The apparatus includes an upper pair of slitter shafts and an upper pair of scorer shafts, as well as a lower pair of slitter shafts and a lower pair of scorer shafts thereby defining two web paths through the apparatus. The web paths are used alternately. All of said shafts are selectively rotated by means of a single motor at one end of the apparatus. A set of trim chutes is provided for each pair of slitter shafts and is located downstream therefrom.

Slitter scorer having upper and lower pairs of shafts selectively

An automatic slitter-scorer apparatus is disclosed for slitting and scoring a corrugated paperboard web. The apparatus includes an upper pair of slitter shafts and an upper pair of scorer shafts, as well as a lower pair of slitter shafts and a lower pair of scorer shafts thereby defining two web paths through the apparatus. The web paths are used alternately. All of said shafts are selectively rotated by means of a single motor at one end of the apparatus. A set of trim chutes is provided for each pair of slitter shafts and is located downstream therefrom.

Slitter scorer apparatus

Upper and lower web guides are pivotably mounted for directing the leading edge of a web to either of upper or lower paths. Each web guide has a plurality of resilient members disposed side by side and extending downstream to define a channel through which the web can pass.

Web diverter

A plurality of flexible panels are disposed side by side and extending in the direction of movement of a web. The panels are supported intermediate their ends by a fulcrum means transverse to the web path. A discrete power means is coupled to each end of each panel for selectively and independently raising and lowering the free ends of the panels while flexing the panels.

Web director

An automatic corrugated paperboard slitter scorer has slitting and scoring heads movable individually or as a group along an expandable shaft by a way of a master shifter. The expandable shaft provides a friction drag to maintain a head in position until all heads are simultaneoulsy locked to the shaft.

Head locking means for automatic slitter scorer

Apparatus is disclosed for slitting a web of material such as paperboard utilizing at least two rotatable turrets disposed one above the other. Each turret has a pair of shafts adapted to have blades selectively positionable thereon by way of a master shifter which adjusts the blades for the next production run on one of the shafts which is in an inoperative position while the other shaft on each turret is in an operative position.

Slitting apparatus

The low speed continuous run feature of a double facer machine is attained by a discrete drive motor coupled thereto by an overrunning clutch. The main drive shaft is coupled to the double facer machine by a fluid operated clutch coupled to circuitry for the double facer machine belt tensioner so that the double facer machine may not operate unless the belt has been tensioned.

Continuous running machines for producing paperboard box blanks

A pan and an applicator roller supported thereby are pivotably supported for movement between operative and inoperative positions by a parallelogram link means including a gear segment. Actuator means is connected to the gear segment for rotating the same in opposite directions.
