An applicator for applying two materials to a substrate includes a central module configured to receive a first material, a tee block configured to receive a second material, a pair of outer modules spaced from and disposed on opposite sides of the central module, each outer module fluidically connected to and configured to receive the second material from the tee block, and a slot die assembly disposed in fluid communication with the central module and the pair of outer modules, the slot die assembly configured to receive the first and second materials from the central and outer modules, respectively, and discharge the first material over a first width and the second material over a second width greater than the first width.

A reusable plastic container is provided. The container includes a plastic container body having opposing side panels and opposing end panels. The container body also includes top side panel flaps attached to a top portion of each side panel, and bottom side panel flaps attached to a bottom portion of each side panel. The container body has top end panel flaps attached to a top portion of each end panel, and bottom end panel flaps attached to a bottom portion of each end panel. The top and bottom side panel flaps are each defined with respect to the side panels by a fold line. The fold lines including at least one scored portion and at least one welded portion.

A flow path sealing structure according to at least one embodiment of the present disclosure, which is disposed on a way of a flow path formed by fusion bonding a pair of resin sheets that are superimposed on each other, includes a widened portion surrounded by a widened seal portion formed by fusion bonding together the pair of resin sheets around a periphery thereof, and one end and another end of which are in communication with the flow path, together with being formed to be wider than the flow path, and a weakly sealed portion formed to extend in a widthwise direction in the widened portion, and which partitions the widened portion in a liquid-tight and airtight manner into the one end and the other end, together with being capable of being opened by increasing an internal pressure of the widened portion.

A sealing apparatus for a secondary battery is disclosed, the sealing apparatus configured to seal a battery case of the secondary battery with an electrode assembly therein. The sealing apparatus comprises: a pair of sealing blocks which press the outer circumferential surface of the battery case; and a heating unit which is provided in the pair of sealing blocks and heat the pair of sealing blocks. The pair of sealing blocks comprise: lead sealing regions configured to press the lead sealing portion of the battery case; and case sealing regions configured to press the case sealing portion of the battery case. The heating unit heats the lead sealing regions and the case sealing regions of the pair of sealing blocks at different temperatures.

The present invention is directed to a heat-sealing apparatus of a flow wrapper machine which facilitates efficient, reliable and versatile operation. Notably, the apparatus includes multiple ring gears driven by multiple servo motors in a desirably compact configuration, with the arrangement including quickly removable heat-sealing die heads for efficient operation and service. The improved drive mechanism facilitates more accurate heat-sealing head placement, smoother operation, controlled stops, independent temperature control, and continuous running through die jams. Also included is a four-bar link on the heat-sealing head for opening and closing the heat-sealing dies.

Method for joining at least two sections of a wind turbine blade, use of an air heater device in a method for joining at least two sections of a wind turbine blade and external heater for use in a method for joining at least two sections of a wind turbine blade

The method for joining at least two sections of a wind turbine blade involves providing an air heater device (3) and with the air heater device (3) supplying a stream of heated air into inner hollow spaces of first (11) and/or second blade sections (12) at least in a joining region (2) and/or placing an external heater (6) on an outer surface of the first (11) and/or second blade sections (12) at least in the joining region (2), wherein the external heater (6) comprises a multitude of heating zones (62-69), wherein a heating power in the heating zones (62-69) is individually controlled.

The method according to the invention improves the curing of a curable resin used to join the blade sections (11,12).

The invention provides a method of manufacturing a pouch for holding therein a liquid, comprising providing a front and back layer, locally bonding them together to create an inner space, forming a pour channel, by locally bonding the layers together to form bonds defining boundaries of the pour channel, wherein the forming of the pour channel is carried out by providing a heating device having a plurality of heating elements arranged in a grid-like manner, forming a heating surface, each of the heating elements being individually operable, operating the heating device such that heating elements which are required for creating the boundaries are operated and thereby heated, and bringing the heating surface into contact with the front layer or back layer, so as to locally bond together the front layer and the back layer so as to form the bonds defining the boundaries of the pour channel.
