A bag making and packaging machine includes a cutter fixed to a sealing member that cuts a laterally sealed portion of a film using pressure force with which a pair of sealing members sandwiches the film during lateral sealing. The bag making and packaging machine further includes a pair of sealing jaws, a knife, a pressurization mechanism, and a pressurization mechanism control part. The knife fixed to one sealing jaw, fusion-cuts the laterally sealed portion of the film. The pressurization mechanism exerts pressure force on one sealing jaw towards the other sealing jaw so that the pair of sealing jaws sandwiches and laterally seals the film therebetween, and the knife comes into contact with a laterally sealed portion and fusion-cuts the laterally sealed portion. The pressurization mechanism control part causes the pressurization mechanism to cease exerting pressure force based on error information pertaining to the film or the goods.

There is provided a sealing apparatus for forming void-fill packaging which includes a longitudinal guide path along which an edge of a part-sealed plastics film material can pass, a drive means for moving the film material along the guide path, and an air blowing or injecting means for inflating the film material. There is also provided a heating element and a rigid thermally conductive member which is thermally coupled to the heating element, the thermally conductive member having an film-contacting surface for applying thermal energy to seal the film material on the longitudinal guide path.

A methods of executing start, run, and stop sequences on a machine for converting a web of preformed pouches into inflated dunnage units. The pouches are defined by transverse seals extending from a remote edge to within a predetermined distance from an inflation edge.

A system holds a roll of film that includes a core and film wound around the core. The system includes a rod having an outer diameter that is smaller than an inner diameter of the core, a proximal wing located on the rod and configured to rotate about the rod, and a distal wing located on the rod and configured to rotate about the rod. Each of the proximal and distal wings includes contact surfaces configured to contact diametrically-opposed locations on a side of an inner surface of the core and non-contact surfaces that span between the contact surfaces of the wing. The non-contact surfaces of the wings do not contact the core if the core has a cylindrical shape. The distal wing is capable of rotating around the rod independently of the proximal wing.

An automatic welding machine for thermally joining sheets of material, in particular for edge side joining of an overlapping upper material sheet to a lower of material sheet, to be connected to one another in a materially bonded manner under the application of heat and subsequent application of pressure, is provided comprising: a heating device for at least partially heating the material sheets to be joined in a connection region; a support frame with a housing; a pressure roller; at least two traveling rollers; wherein the pressure roller and the traveling rollers are arranged on the support frame and together with the support frame form a chassis, wherein the chassis comprises a longitudinal axis and a transverse axis perpendicular thereto, which span a chassis plane; wherein at least a first travelling roller of the two travelling rollers and/or the heating device is arranged to be movable by a telescopic pull-out relative to the support frame in directions parallel to the transverse axis; wherein the first travelling roller and the heating device are with respect to a longitudinal center of the chassis arranged on opposite sides of the chassis. Further a corresponding method is provided.

A system for opening and closing a mixing manifold includes a drive motor, a cam plate, and a valving rod connector. The drive motor imparts movement in first and second directions. Movement imparted in the first direction causes the cam plate to move linearly in a third direction and movement imparted in the second direction causes the cam plate to move linearly in a fourth direction. Movement of the cam plate in the third direction causes the valving rod connector to move linearly in a fifth direction and movement of the cam plate in the fourth direction causes the valving rod connector to move linearly in a sixth direction. Movement of the valving rod connector in the fifth direction causes retraction of a valving rod of the mixing manifold and movement of the valving rod connector in the sixth direction causes extension of the valving rod.

A layered body containing continuous sheets is thermally fused when passing through a space between an anvil roll and an energy applying device to form a layered sheet. A nip stage for sandwiching the layered body is provided upstream of the space between the anvil roll and the energy applying device. The nip stage includes at least one displacement member which is displaced in accordance with the thickness of the layered body sandwiched by the nip stage. Whether the thickness of the layered body sandwiched by the nip stage has deviated from a reference range is detected on the basis of the displacement of the displacement member, and when it is detected that the thickness has deviated from the reference range, the energy applying device is caused to retreat in a direction going away from the anvil roll.

A portable table top welder for welding plastic material webs, the portable table top welder including a frame including a carrier housing and a support arm at which a welding device is arranged; at least one transport roller including a rotatable transport roller axle and at least one contact pressure roller that is rotatably supported at the carrier housing, wherein a weight is arranged at an eccentrical element which is rotatably connected at one side by a concentrically supported eccentrical element axle at the carrier housing and rotatably connected at another side by an eccentrically supported contact pressure roller axle at the contact pressure roller. The table top welder handles and transports easily and can be mounted on a table or on another carrier structure in a disengageable manner.

A pouch machine vertical sealer capable of fusing a pouch film web to form a plurality of spaced vertical seals along a length of the film web to form pouches. The pouch machine vertical sealer includes a sealer wheel rotatable about a vertical axis of rotation and defines a film web path about a periphery of the sealer wheel. The vertical sealer further includes a plurality of vertical sealer land assemblies spaced apart about the periphery of the sealer wheel. Each vertical sealer land assembly includes an impulse heater such that contact between the film web and each impulse heater of the plurality of vertical sealer land assemblies forms the spaced apart vertical seals along the length of the film web.
