摘要： A conveyor surface for carrying off separated sheets in a web welding and separating machine is displaced from a welding gap between a welding roller having a welding tool and an opposing roller in the direction of the axis of the opposing roller. As the leading edge of a thin web passes beyond the welding gap, it tends to stay close to the surface of the opposing roller until it has been borne a substantial circumferential distance past the welding gap, whereupon it separates therefrom. A guide plate bridges a space between the opposing roller and the conveyor surface to smoothly transfer the separated sheets to the conveyor surface. An elastically compressible strip on the welding roller is optionally used to improve the separation of the leading edge of the web from the welding tool and to closely press it against the opposing roller.

摘要： A flexible bag construction and a method for producing the bag. The construction is formed from flexible plastic films located in overlying relationship with one film defining a return portion having a free edge positioned inwardly from the top of the bag. A second free edge is defined by a separate film portion in spaced relationship relative to the first free edge. A flexible plastic strip is introduced between the return portion and the opposing film and this strip is heat sealed in place. The second free edge provides a means for inserting articles into the bag whereby the bag can be used for merchandising purposes, particularly after being sealed along the second free edge. An opening is preferably formed in the top of the bag extending through overlying film portions and the intermediate strip to provide means for suspending the bag.

摘要： A packaging material for reclosable bags and methods for making same. The material includes a standard packaging material substrates including an initial seal layer, typically for forming a heat seal. A layer of a secondary seal material, typically a tacky material such as a pressure sensitive adhesive is applied in localized areas corresponding to the seal area for the bag. The initial seal layer may have a reduced thickness in this localized area to reduce thickness variation in the finished material. An outer seal layer is provided over the secondary seal area. This outer seal layer may be localized to cover only the secondary seal layer. The outer seal layer may additionally or alternatively have a reduced thickness in the localized area of the secondary seal layer to again reduce thickness variation. Various process are available for providing the layers. In one embodiment, the secondary and outer seal layers are applied by use of a ribbon coater. This application may be directly upon the substrate, or upon a release sheet for later transfer to the substrate.

摘要： A mass airflow sensor is disclosed which uses a small, thin dielectric diaphragm providing good thermal isolation for thin-film heating and temperature sensing elements, resulting in high flow sensitivity and low current operation of the heating element. The dielectric diaphragm is bounded by a p-etch-stopped silicon rim. The mass airflow sensor includes a primary sensor circuit which maintains a heated primary temperature sensing element and an ambient air temperature sensing element at a constant temperature difference. A slave sensor circuit, which includes a plurality temperature sensing elements, monitors heat loss due to airflow at a particular location on the diaphragm and generates an output signal indicative of airflow which is independent of ambient air temperature.

摘要： Bags for packaging cut tobacco are severed from a continuous longitudinally moving film sheet along transverse welding seams 28 which are made by a thermal welding unit 29 having three, transverse-welding jaws, during each working cycle. The welding unit can be moved to and fro and is movable with the film sheet 25 for a part section (conveying section). During the return movement of the welding unit to its starting position, the film sheet is conveyed onwards by a special draw element, until a conveying cycle has been completed.
