A coating apparatus for double-sidedly coating a porous web with a dope, includes: (i) a slot-die coating head comprising an upper lip, a lower lip and a slot between the upper lip and the lower lip, (ii) a counter element arranged opposite the lower lip across a reference plane, (iii) a slit defined between the lower lip and the counter element for passing a porous web therebetween, the slot opening up towards the slit, and (iv) a web positioning element. The web positioning element is the upper lip of the slot-die coating head. The upper lip protrudes up to the reference plane so that there is an offset between the upper lip and the lower lip, or a spacing structure on the counter element. The spacing structure protrudes up to the reference plane so that there is an offset between the spacing structure and the counter element.

An apparatus for manufacturing an elastic composite structure for an absorbent sanitary product includes an anvil with weld pattern comprising at least one anchoring region and at least one deactivating region. The anchoring region includes anchoring welds that form anchoring bonds that fuse facing web layers and anchor elastic thread(s) in position relative to the facing web layers. The deactivating region includes a break bar constructed to sever the thread(s). A method of manufacturing the elastic composite structure includes positioning a tensioned elastic thread between web layers, fusing the web layers to form an anchored zone that includes anchoring bonds that fuse the web layers and anchor the tensioned elastic thread therebetween, and cutting the thread to form a deactivated zone between adjacent portions of the anchored zone that is free of tensioned threads. The method further includes fusing the web layers within the deactivated zone.

A device for applying liquid flavors to collagen casing is provided. In one embodiment, the device comprises a cup and a roller for applying liquid flavor to the surface of the collagen casing prior to drying. In another embodiment, the device comprises an applicator having a base plate with a first hole in the base plate to allow the collagen casing to pass through the base plate, a second hole in the base plate in fluid communication with the first hole to inject liquid flavor through the second hole into contact with the collagen casing as it passes through the first hole, a wiper removably attached to the base plate to wipe excess liquid flavor from the surface of the collagen casing, and a liquid flavor injection line attached to the second hole in the base plate. In some embodiments, the cup and roller are combined with the applicator to apply the liquid flavor.

An air knife includes: a nozzle main body provided so as to inject gas in response to the width of the steel plate; a nozzle lip installed on at least one of the upper section and the lower section of an outlet of the nozzle main body and extending inclinedly so that the injection cross-sectional area of the gas becomes narrow; and at least one moment generation unit, provided at one side of the nozzle lip, for generating a rotation moment so that the nozzle lip is curved in the width direction of the steel plate and a gap between other nozzle lips varies.

An apparatus for producing a roll of waxed fabric is provided, the apparatus comprising: a frame; a temperature controlled bath at an entrance end of the frame; a squeegee pressed against an exit side of the temperature controlled bath; a cooling tower adjacent the temperature controlled bath, the cooling tower including walls and a manifold to define a cooling zone, the manifold for delivering a flow of air to the cooling zone, a tower roller rotatably mounted above the cooling zone and a lower roller rotatably mounted proximate an exit side of the cooling tower; a blower for delivering air to the manifold; a collection roller rotatably mounted adjacent the alignment roller; a driver roller in rolling engagement with the collection roller; and a motor in mechanical communication with the driver motor for driving the driver motor. A method of producing a roll of waxed fabric is also provided.

Assemblies and methods of use are disclosed for repairing the coating of a coated wellbore line. A wellbore line can be cleaned and then coated with a repair material before being pulled through a die to shape the coating and then being pulled through setting section to set the repair material. The repair material can be a thermoplastic material that is set by cooling, or a thermoset material that is set by heating. The wellbore line can be repaired upon exiting a wellbore or being unspooled from a reel.
