摘要： When sheet products 1 are discharged, the sheet products are collided against shutter bars 5 so as to fall and stack on a feed conveyor 4. Then, each of protrusion bodies 7 and 8 are lowered by a first drive 9 so as to nip the sheet products between the protrusion bodies and the feed conveyor . Then, coming products are successively discharged and stacked on the protrusion bodies. And then, a second drive 12 is operated in conjunction with the feed conveyor so as to feed the sheet products nipped between the protrusion bodies and the feed conveyor 4. The shutter bars 5 are elevated and lowered by a third drive for adjusting the height position thereof.

摘要： A cooking bag enclosing a food item to be cooked therein is disclosed. The cooking bag may include a foil pouch having a foil pouch interior surface defining a food pocket therein for receiving and storing the food item and isolating the food item from an ambient atmosphere surrounding the foil pouch. A removable printed film sheet may be affixed to a foil pouch exterior surface by a releasable adhesive. The removable printed film sheet may be separable from the foil pouch exterior surface by peeling the releasable adhesive without breaking the foil pouch and exposing the food pocket and the food item to the ambient atmosphere. The food item may then be cooked in the foil pouch on a grill, in an oven, on a stove or with another appropriate heat source.

摘要： A reclosable package (10) is described that includes inner and outer film layers (20, 15). Each of the inner and outer film layers (20, 15) includes die cuts (25, 35) that are designed to create a peelable flap portion (30) that, when pulled back by the user, reveals an opening of the package for providing access to the contents of the package. In particular, the inner film layer (20) has an inner die cut (35) that includes a cross-directional cut line (55). While the cross-directional cut line in conventional packages is a straight line, the package described herein uses a line that has one or more radii of curvature. In this way, the vibrations that may otherwise be generated during the rotary die cutting process are reduced, and more consistent cut depths can be achieved.

摘要： Apparatus and methods for manufacturing a folder which has front and back panels with a divider therebetween. The divider front and back panels and divider are tape d together along a spine of the folder such that the panels and divider can be turned like the pages of a book. There may be one, two, or three or possibly even more dividers with al l of the dividers being secured in place at the spine of the folder. The tape(s) may be pleated so that the panel-to-divider and/or divider-to-divider compartments can expand. This pleating technique can also be employed to give expansibility to the single compartme nt of a file folder which does have internal dividers.

摘要： Methods of making a container strip in the form of a chain of interconnected preopened bags with openings preferably having longitudinal dimensions of at least about 1/64 inch is disclosed. The container strip provides greatly enhanced facility for bag registration and opening during packaging operations utilizing the improved container strip. Processes of forming a chain of preopened bags are also disclosed. Face (14) and back (5) plastic webs are fed along individual paths of travel to a common path (28). In one embodiments the webs are differentially tensioned while in their independent paths by stretching the face web, by rollers (18) more than the back web by rollers (20) such that the face web will retract longitudinally more than the back web upon release of the web tension. While so tensioned edge seals are formed between the webs to convert the webs into a tube and longitudinally spaced transverse seals are formed between the webs to delineate bottoms of bags. Transverse lines of weakness are formed in said back web to facilitate separation of bags from the remainder of the web during a subsequent use. Tension in individual bag sections of the face web is released by forming longitudinally spaced transverse separations of the sections and thereby producing a space between each contiguous pair of sections. In other embodiments, pairs of transverse lines of severance are formed in a front section of the webs and parts between the lines of severance are removed to form the novel bags without the need for differential stretching.
