An article of manufacture comprises a plurality of nested plastic bags for use in lining containers such as garbage cans or waste paper baskets. The assembly is manufactured by placing successive plastic bags over a jig. The upper edges of the plastic bags are adhered to each other, for example, by conventional heat sealing means. The adherence between individual bags is such that the innermost bag can be separated readily from the remaining bags after the assembly is placed within a container.

Nested plastic bags and method of manufacture

Disclosed is a bag including a front wall and a rear wall and having an open mouth portion in which the front wall and rear wall are joined by pleated portions or gussets. The bag is manufactured so that a longitudinal, thermally welded seam is placed inside a portion of at least one of the gussets at a point other than the central fold. The bag preferably includes handles which are integral extensions of the front and rear walls and the gussets. The bag manufactured according to the principles of the present invention thus eliminates or minimizes failure of thermally welded seams. Also disclosed is a method for manufacturing the bags and an apparatus for manufacturing the bags.

Plastic bag and method and apparatus of manufacture

Apparatus is provided for automatically effecting a widthwise folding of a long, flexible web advanced therethrough. The web is trained about a first roller at a point where the folding begins and about a second roller at a point where the folding ends. A displacement edge or bar is mounted in a fixed location equidistant from the first and second rollers, and a portion of the web is trained about the displacement edge or bar during the folding. Webs of different widths are accommodated by adjusting the positions of the first and second rollers without changing the shapes of three similar triangles. The first triangle is defined by a first point where a first edge of the web intersects the first roller, a second point where the same edge of the web intersects the second roller, and a third point where the opposite edge of the web intersects the first roller. The second triangle is defined by the first point, a fourth point where the first edge of the web intersects the displacement bar or edge, and a fifth point midway between the first and second points. The third triangle is defined by the second, fourth and fifth points. The distance between the fourth and fifth points is half the distance between the first and second points.

Apparatus for folding sheet materials

A dispenser for plastic bags comprises two side panels, top and bottom panels and a back panel forming a rigid container. A front panel is hingedly connected to the bottom panel for closing the container. The front panel is formed with a perforated pull-out in the mid to lower portion whereof to expose the interior of the container. A generally U-shaped hanger has a base lying outside the container near the top thereof to facilitate securing the container to an outside support and has a pair of arms passing through and secured by the back and front panels near the respective tops thereof. The arms are adapted to pass through holes formed in the bindings of pads of plastic bags to support the pads within the container. When the pads of bags are thus supported within the container and the perforated pull-out is opened, the bags can be conveniently removed singly by users.
