Appl. No.:

10/199339

International Classification:

B26D007/06

US Classification:

083/029000, 083/436300

Abstract:

A method of automatic in-line forming of a material stack comprising the steps of feeding a base in sheet form or from a roll to a predetermined position, simultaneously feeding a first layer from a first roll for placement on one side of the base in sheet form and a second layer from a second roll for placement on the opposite side of the base in sheet form. The base, the first layer from the first roll, and the second layer from the second roll are moved together to a cutting station and are advanced a predetermined length. The first layer and the second layer are cut together to the predetermined length to form the desired stack, with the base between the first and second layers. In another aspect, the invention comprises apparatus for automatic in-line forming of a material stack comprising a main frame, a conveyor on the main frame for feeding a base material. A first layer of material is fed from a first roll onto one surface of the base material. A second layer of material is fed from a second roll to the opposite surface of the base. A third roll can be provided from which a third layer is fed onto the first layer. Pinch rollers are provided for moving the base material, the first layer, the second layer and the third layer to a cutting station. A gripper mechanism is associated with the pinch rollers for pulling out a predetermined length of material to be cut when the pinch rollers are released. A fixed blade is provided on one side of the stack and a movable blade is provided on the other side of the stack. The movable blade cooperates with the fixed blade for cutting the predetermined length of material together to form the desired stack of material on both sides of the base material. Controls are provided for coordinating the operation of the pinch rollers, the gripper mechanism, and the fixed and movable blades.

US Classification:

270/052140

Abstract:

A cover sheet applicator for applying a cover sheet from a roll, for example, paper or plastic, to a sheet of material, for example, glass or screen printed adhesives. The applicator comprises a frame and a first conveyor for receiving a sheet of material to be covered. Cover material is drawn from the roll by drive rollers. A cutting mechanism cuts the cover material to a predetermined length to form the cover sheet. The cover sheet is received and retained on a vacuum conveyor which is inclined with respect to the first conveyor, for example, an endless belt. A control is provided to sequence the operation of the first conveyor, the cutting mechanism and the vacuum conveyor. When the lead edge of the cover sheet and the sheet of material are aligned, the vacuum is released and upon further advance of the sheet of material, the cover sheet is applied to the top of the sheet of material.

International Classification:

B26D 130

US Classification:

83584

Abstract:

A cutting machine for sheet material comprising a frame, a stationary knife on the frame and a reciprocating blade cooperating with the stationary knife. A motor on the frame is connected to a gear reducer that is in turn connected to a single push rod through a crank. The push rod is operatively connected to a torque tube that is connected adjacent its ends by link means to the reciprocating blade. Rotation of the crank by the gear reducer will actuate the single push rod and the torque tube operatively connected thereto to reciprocate the reciprocating blade. Spring means for assisting movement of the reciprocating blade are readily adjusted from exterior of the frame of the cutting machine. A rotatable cam follower on the reciprocating blade engages a guide block on the frame for moving the reciprocating blade into proper cooperative engagement with the stationary knife in use.

International Classification:

B26D 520
B26D 118

US Classification:

83215

Abstract:

A cutting machine for cutting long lengths of sheet material, roll material, or web material into predetermined or discrete lengths comprises a frame having a stationary blade extending transversely of the frame and a carriage movable transversely of the material to be cut having a movable blade thereon that cooperates with the stationary blade to cut material. The movable blade is mounted on the carriage so that it can be canted at an angle with respect to the stationary blade during transverse movement of the carriage in one direction and can be oppositely canted at an angle with respect to the stationary blade during movement of the carriage in the opposite direction. In one embodiment, a toggle mechanism is used to cant the movable blade. In a second embodiment, a fluid cylinder is used to cant the movable blade.

International Classification:

B26D 138

US Classification:

83 63

Abstract:

A machine for feeding and cutting sheet material includes a housing and a framework pivoted on the housing to permit loading of sheet material into the machine. A feed roll is journalled in the housing. A cooperating pressure roll is journalled on the framework. A spring is adjustably carried on the framework for adjusting the pressure of the pressure roll toward the feed roll. A knife blade on the framework, and fixed to the framework cooperates with a movable knife blade in the housing for cutting predetermined lengths of sheet material. A cam follower bearing is provided in the housing to help guide movement of the knife blade in the housing. A spring adjustment is provided in the linkage connecting the cylinder driving the movable knife blade and the movable knife blade for varying the force of the movable knife blade against the cam roller bearing. A safety interlock in circuit with the drive motor for the feed roll will stop the drive motor when there is a jam of sheet material in the machine in use or if the framework is open.
