Parallel method for packaging electronic component and coating adhesive on carrier tape and mechanism for same
The present invention provides a parallel method for packaging an electronic component and coating an adhesive on a carrier tape and a mechanism for same, so as to regulate continuous output of an adhesive and intermittent movement in packaging work, so that during a short pause of placing an electronic component, a continuously output adhesive is prevented from being repeatedly applied at a fixed position of a carrier tape. In this way, excessive application of an adhesive can be avoided, and it can be further ensured that the quality of packaging is not affected by an excessive amount of an adhesive.
Air cushion inflation machine
A machine for converting two different types of webs of inflatable material to two different types of inflated cushioning material includes an inflation arrangement, a sealing arrangement, and a tensioning device. The inflation arrangement is configured to provide air at a lower pressure to a first web of a first type of inflatable material to inflate the first type of inflatable material, and to provide air at a higher pressure to a second type of inflatable material to inflate the second type of inflatable material. The inflation arrangement includes a guide pin configured to the first and second webs and align the first and second webs on the machine. The sealing arrangement is configured to seal the first type of inflatable material and the second type of inflatable material to create the two different types of inflated cushioning material. The tensioning device is configured to provide a lower tensioning force to the first web as the first web moves between the inflation arrangement and the sealing arrangement, and to provide a higher tensioning force to the second web as the second web moves between the inflation arrangement and the sealing arrangement.
WELDING STATION FOR AN INSTALLATION FOR MANUFACTURING PACKAGES WITH PADS
A welding station for an installation for manufacturing packages with pads, the welding station including a plurality of longitudinal welding heads. Each welding head is configured to weld to one another two superposed sheets as said sheets advance in a first direction and may include a welder to apply heat on an action area. Each welding head has a main body, a first traction belt wound in the main body and a second traction belt wound to said main body, parallel to the first traction belt and separated from the first traction belt by a separation gap in a second direction which is transverse to the first direction. The action area is arranged in said separation gap, between both traction belts. Each of the longitudinal welding heads is configured to be able to be moved along the second direction.
Frame assembly for surface mount technology stencil
A framed stencil for surface mount technology (SMT) is provided. The frame assembly includes a frame member and a binding insert. The frame member includes an inner perimeter portion and an outer perimeter portion that cooperates with the inner perimeter portion to define an elongated channel. The outer perimeter portion includes a first cantilever portion that extends over the elongated channel and towards the inner perimeter portion. The binding insert is configured for releasable insertion into the elongated channel. The binding insert includes a base and a tongue. The base configured to interface with a mesh substrate to facilitate coupling therebetween. The tongue is coupled to the base and extends substantially horizontally from the base. When the binding insert is inserted into the elongated channel, the tongue extending beneath the first cantilever portion to facilitate retention of the binding insert to the frame member. Methods are also provided.
SEALS FOR AERIAL VEHICLES
Aspects of the disclosure relate to envelopes for aerial vehicle. The aerial vehicle may include an envelope including a plurality of gores. The aerial vehicle may also include a seal arranged between a pair of the plurality of gores, the seal including six layers of envelope material heat-sealed together.
Tube Seal and Cut Device
A tube seal apparatus including a sealing iron having a tube sealing end, an insulating shroud having a tube clamping end, wherein the sealing iron is at least partially disposed within the insulating shroud. The apparatus further includes an anvil having a cutting detail and a non-stick membrane disposed between the anvil and the tube clamping end of the insulating shroud. The sealing iron and insulating shroud are configured to advance towards a tube to be sealed positioned between the non-stick membrane and the anvil. The tube clamping end is configured to clamp the tube through the non-stick membrane. The sealing iron is configured to advance towards the tube to melt and seal the tube against the cutting detail through the non-stick membrane.
Methods and apparatuses for assembling elastic laminates with different bond densities for absorbent articles
The methods herein relate to assembling an elastic laminate with a first elastic material and a second elastic material bonded between first and second substrates. During assembly, an elastic laminate may be formed by positioning the first and second substrates in contact with stretched central regions of the first and second elastic materials. The elastic laminates may include two or more bonding regions that may be defined by the various layers or components of the elastic laminate that are laminated or stacked relative to each other. In some configurations, a first plurality of ultrasonic bonds are applied to the elastic laminate to define a first bond density in the first bonding region, and a second plurality of ultrasonic bonds are applied to the elastic laminate to define a second bond density in the second bonding region, wherein the second bond density is not equal to the first bond density.
Method for forming elastic film stretchable structure, and absorbent article
Ultrasonic welding is performed by passing a first sheet layer, a second sheet layer, and an elastic film interposed therebetween in a stretched state in a machine direction between an anvil roll having a large number of protrusions and an ultrasonic horn. The anvil roll includes a region having the protrusions and in the region. A site, in which welding is performed by one ultrasonic horn, has a portion in which an area rate of the protrusions changes in a roll circumferential direction and a roll length direction. A difference between a maximum value and a minimum value in a change of the area rate of the protrusions in the roll circumferential direction is 4.5% or less, and a difference between a maximum value and a minimum value in a change of the area rate of the protrusions in the roll length direction is 1.5% or less.
Disposable wearable article
A disposable wearable article includes an elastic film stretchable structure in which an elastic film is laminated between a first sheet layer and a second sheet layer. The first sheet layer and the second sheet layer are bonded to each other through holes passing through the elastic film with many bonded portions arranged at intervals. A region having the elastic film stretchable structure includes a stretchable region that elastically stretches and contracts together with the elastic film. The stretchable region includes a plurality of elastic films disposed so as to have an overlapping portion. The number of laminated layers of the elastic film in a region located in an intermediate portion of the stretchable region in an orthogonal direction (XD) orthogonal to a stretchable direction (ED) is different from that in each of second regions adjacent to both sides of the first region.
Air cushion inflation machine
A machine includes an inflation arrangement, a sealing arrangement, and a tensioning device. The inflation arrangement provides air at a first pressure to inflate a first web of a first type of inflatable material, provides air at a second pressure to inflate a second web of a second type of inflatable material, receives the first and second webs, and aligns the first and second webs on the machine. The first pressure is different from the second pressure. The sealing arrangement seals the first and second types of inflatable material. The tensioning device provides a first tensioning force to the first web as the first web moves between the inflation and sealing arrangements and provides a second tensioning force to the second web as the second web moves between the inflation and sealing arrangements. The first tensioning force is different from the second tensioning force.
