An adjustable card folding station includes an adjustable vacuum bed and moveable gates. The vacuum bed includes at least two sections that are movable with respect to each other to accommodate cards of different widths. Each section of the vacuum bed further includes multiple suction cups, each of which is individually connected to a vacuum supply. The vacuum supply independently controls each suction cup so that vacuum can be applied to selected or all suction cups such that cards of different lengths can be accommodated. The movable gates are pivotally mounted with respect to the vacuum bed and operated by motors to pivot 180 degrees from open to closed positions to fold the cards.

The method is one of producing multi-ply laminates incorporating an exposed veneer in quality wood or cork, and involved bonding the veneer (1) to a thin flexible thermoplastic film (2) by way of a layer of hot melt adhesive (3). The same laminate can be reinforced to enable its use in manufacturing sewn goods, such as bags and acessories, by ading a tough, close-woven backing fabric (20), bonded to the back of the film (2) in similar fashion via a further layer of adhesive (3), which provides the strength necessary to take a heavy stitch when sheets are sewn together.
摘要:
An automotive headliner comprised of a laminate of double corrugated paperboard. Perforations in all the sheets of the laminate except the back paperboard sheet improve the acoustical performance of the liner. A vapor barrier on the back sheet prevents entry of moisture into the laminate from the roof, and a layer of sound dampening material on the front face of the laminate improves the sound absorption of the laminate. The front corrugation is larger than the back corrugation. When molding the laminate it is first moisturized, then heat molded. Heat is applied until the laminate has regained its rigidity.
摘要:
A heat shapable resin laminate sheet, composed of several heat-bonded support webs impregnated with duroplastic binders, the deformation temperature to be utilized in shaping the laminate sheet being higher than the temperature utilized in molding it, which comprises a number of individual laminations, each of which is formed separately of one or more support webs impregnated with duroplastic binders and layers of thermoplastic binders arranged between the individual laminations, the melting point temperatures of the thermoplastic binders being equal to or lower than the deformation temperature, and a process of shaping the laminate sheet.

A process and a device for folding a foldable sheet, in particular a map sheet, made of stiff paper or plastic, which is star-folded, in which the outward folds (13,14) and inward folds (12) that meet at the center point (M) of the sheet (10) are formed simultaneously by V-shaped carriers (33a and 33b) and first folder elements (37a,37b) that can be swung upwards perpendicular to these and in which, when the halves (10a,10b) of the sheet (10) that are defined by the outward folds (13,14) are folded together the corner inward folds (23,24) are made by second folder elements (71a,71b) that are articulated onto the side edges (72) of the carriers (33a,33b) and swing down on these, whereupon the two folded halves (10a,10b) of the sheet (10) are pressed together between the carriers (33a and 33b), the clamping plates (45), the second folder elements (37a,37b) before the folded sheet that has been folded together is grasped by the gripper (40) and withdrawn between these plates after the designated plates have been depressurized.
摘要:
A device for wrapping a substantially flat piece of sheet material with a plurality of creases that define fold lines that when folded, forms an elongate structure that includes a hollow outer portion and a hollow inner portion disposed within the hollow outer portion. The device includes a mandrel, a gripper blade that releasably secures the sheet material to the mandrel, a motor that rotates the mandrel when the sheet material is secured to the mandrel, and a compressive member that releasably presses the first outer side surface of the hollow outer portion of the elongate structure against the inner portion of the elongate structure after the sheet material has been wrapped about the mandrel. The device can also include a controller that is operably associated with the motor and the compressive member.
摘要:
Systems for folding a receiver having a dry toner thermally fused thereon are provided. In one aspect, a system for folding has a wetting system adapted to apply water along a fold line and a fold mechanism folding the receiver along the fold line. The folding is performed after a predetermined absorption period during which at least a portion of the applied water is absorbed by the receiver to reduce the extent to which the receiver cracks proximate the fold line during folding.
摘要:
A machine for producing articles of sheet material, having a conveyor with powered rollers for feeding blanks along a path; pressure devices for holding the blanks in contact with the powered rollers; and operating devices which interact with the blanks to perform operations, in particular folding and gluing operations, on the blanks as the blanks travel along the path. The conveyor has a number of drive members arranged along the path, and to which the pressure devices are connectable by universal transmission assemblies.
摘要:
A paper folding machine is provided including a housing having upper and lower fold plates constructed for quick and easy removal of the upper plates from the machine so that repairs may be made. The machine includes an automatically adjustable stacking arm movable to positions corresponding to the settings of the machine for fold type and size.
