摘要： Method and apparatus for making an easy open substantially rectangular bag of compressed flexible articles having a handle extending in a direction substantially parallel to the direction of compression of the articles. The preferred method includes the steps of: (a) providing at least two discrete portions of a continuous line of weakness in a web of flexible material; (b) forming a "W"-shaped cross-section in the web; (c) feeding a web of the material forming the handle parallel to the web of bag material; (d) nesting the web of handle material within the web of "W"-shaped material; (e) sealing the nested webs to one another forming unerected flexible bags; (f) severing the discrete unerected flexible bags from the web in the sealed areas of the web; (g) partially erecting each flexible bag; (h) forming a stack of flexible articles; (i) compressing the stack of flexible articles between a pair of opposed knife belt assemblies; (j) moving the knife belt assemblies and the partially erected bags relative to one another so that the knife belt assemblies pass into the partially erected bags; (k) simultaneously driving the opposed knife belts in a direction which advances the stack of compressed articles into the partially erected flexible bag; (l) moving the knife belt assemblies and the partially erected flexible bags relative to one another so that the knife belt assemblies are completely retracted from each of the flexible bags; (m) folding the open bottom end of each bag to form a closed bottom panel; and (n) securing the bottom panel in a closed position to complete the bag.

摘要： An apparatus is provided for continuously sealing a thermoplastic draw tape to a thermoplastic bag at a sealing section. The bag forms one of a plurality of bags formed on a continuous web of thermoplastic material. The bag includes a hem defining a channel wherein the draw tape is disposed. The section of the bag which includes the hem and the tape thus includes a plurality of layers of thermoplastic material. The apparatus comprises a conveyor for continuously moving the web; a first sealing station for forming a heat seal through at least two of the layers of the hem and tape, the seal being formed on a first side of the bag; and a second sealing station for forming a heat seal through the rest of the layers of the hem and tape at the sealing section on a second side of the bag. The first and second sealing stations form the seals while the web is continuously moved by the conveyor.

摘要： A thermoplastic tape having thick and wide end portions with a relatively thin and narrow stretched central portion between them is produced by a first pair of nip rolls running at a slow speed, and a second pair of nip rolls running at a higher speed. The tape between the nip rolls is intermittently moved away from, and toward said first nip rolls to stretch it to produce the relatively thin and narrow central portion. The second pair of nip rolls is mounted on a pivoted arm so that they are movable toward, and away from said first nip rolls. Alternatively, an idler roll between the two pairs is moved toward, and away from, the first nip rolls.

摘要： A method of making a gift bag which contains a pair of ribbon loops in the neck which, when pulled in opposite directions, form a cluster at the top of the bag about which the ribbons can be tied to form a fancy package.The method of in-line production of such gift bags includes laying a pair of ribbons near opposite edges of a sheet and folding the edges to form flaps over the ribbon; folding the sheet longitudinally at the middle, punching spaced-apart holes in the sheet-enfolded flaps at intervals corresponding to the width of the bag; guiding the ribbons into registry with the punched holes; sealing along a transverse zone passing through the middle of the punched hole and cutting along the transverse zone to separate the bags.

摘要： An easy open flexible bag preferably containing one or more stacks of flexible articles which are maintained in a state of compression in a direction substantially parallel to their thickness. For products such as disposable absorbent baby diapers, catamenial pads, incontinent briefs and the like, the degree of compression within the bag may be as much as 50% or more when compared to the uncompressed thickness of the stack of articles in question. In a particularly preferred embodiment, the bag totally encloses the stack or stacks of compressed flexible articles and exhibits a substantially rectilinear shape. The bag preferably includesa longitudinally oriented carrying handle which is formed indepenently of the bag. The opposed ends of the carrying handle are preferably secured to bag's side panels. The side panels and the front and back panels of the bag are subject to tension imposed by the stack of compressed flexible articles. A predetermined line of weakness spanning a tensioned side wall of the bag is provided and functions as an easy opening system. The easy opening system is so positioned on the side panel of the bag that when the package is opened, the carrying handle remains attached to the bag and fully functional. The easy opening system allows the compressive forces acting upon the flexible articles contained in the bag to be partially relaxed when the easy open feature is activated by the end user. Partial separation or complete removal of a portion of the tensioned side panel of the bag allows the coinciding portion of the stack of compressed articles to project in fan-like array through the aperture thus created to permit easy one-at-a-time removal.
摘要翻译：一种容易打开的柔性袋，优选地包含一个或多个柔性制品堆，所述柔性制品在基本上平行于其厚度的方向上保持在压缩状态。对于诸如一次性吸收性婴儿尿布，月经垫，失禁内裤等的产品，与所讨论的物品堆的未压缩厚度相比，袋内的压缩度可以高达50％或更多。在一个特别优选的实施例中，袋完全包围压缩的柔性制品的堆叠或堆叠并且呈现基本上直线形状。该袋优选地包括一个纵向取向的携带手柄，该手柄独立于袋子形成。携带把手的相对端部最好固定在袋子的侧面板上。袋子的侧面板和前面板和后面板受到压缩的柔性制品的堆叠施加的张力。提供了跨越袋的张紧侧壁的预定的弱线，并且用作容易打开系统。容易打开系统位于袋的侧面板上，当包装打开时，携带手柄保持附着在袋子上并且完全起作用。当容易打开的特征被最终用户激活时，容易打开系统允许作用在包装袋中的柔性物品上的压缩力部分地松弛。部分分离或完全去除袋的张紧侧板的一部分允许压缩制品堆叠的重合部分通过如此形成的孔突出成扇形阵列，以允许一次一次的移除。

摘要： A thermoplastic draw tape having thick and wide end portions with a relatively thin and narrow central portion between them is produced by movable clamps which stretch the tape between stationary clamps to produce the stretched, oriented portions of the tape. A plurality of movable clamps and a plurality of stationary clamps produce a plurality of stretched central portions so that the stretching time can be greater than the cycle time of bag making machinery with which the stretching apparatus is synchronized.

摘要： A process for manufacturing draw tape bags, unique tubular films used in the process and the resulting draw tape bags are disclosed. The process begins with the step of forming a tubular film having a longitudinal region with a film strength greater than the film strength of the remainder of the tube. Next, the longitudinal region of greater strength is slit out of the tube and into draw tape ribbons, leaving the remainder of the tube in the form of a continuous sheet with two side edges. A hem with a draw tape access hole is next formed from each of the two side edges, each of the hems encasing a draw tape ribbon. Last, transverse seams are formed in the folded continuous sheet to define individual bag edges and the folded continuous sheets is severed to form individual bags. In one embodiment the longitudinal region of greater strength is made from a resin different than the resin making up the remainder of the tube. In another embodiment the tubular film is formed with the region of greater strength being thicker in its cross-section than the cross-section of the remainder of the film. The resulting bag has a draw tape which is made from film severed from the marginal portion of the bag wall but which has a greater strength than the bag wall film.

摘要： Draw tape bags are made with folding surfaces which decrease in width to the final bag height. One edge of each side of a moving web of film is tucked onto a side of a surface to produce a hem in each edge of the moving web. Rollers, which are canted with respect to the direction of movement of the web, pull the hem of the film tight against the surface to insure that the web is at the final bag length when the web leaves the surfaces.
