A packaging machine including a hot plate assembly adapted to fuse a length of heat-sensitive film wrapped around a package. A controller is adapted to calculate a time period the heating element is energized to fuse the length of heat-sensitive film wrapped around the package based on an initial temperature of the heating element. A hot plate status indicator is adapted to indicate at least to different statuses of operation of the packaging 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.

A disclosed apparatus for forming a sealing portion for folding a secondary battery pouch includes: first and second pressing bars disposed to face each other with a sealing portion for folding therebetween to apply pressure for flattening the sealing portion for folding that is defined by the edge of a secondary battery pouch for sealing an electrode assembly accommodated therein; first and second pressing surfaces provided at the first and second pressing bars, respectively, and disposed to face the sealing portion for folding; and a forming protrusion formed on the first pressing surface and configured to form a folding guide line on the sealing portion for folding by pressure applied by the first and second pressing bars.

A disclosed heater for a sealing process of a secondary battery includes: a sealing bar heating and pressing a pouch foil to be sealed; a plurality of sub-heating unit longitudinally disposed inside the sealing bar to respectively independently supply heat to a plurality of sections separated in the longitudinal direction of the sealing bar; temperature sensing units disposed inside the sealing bar and sensing temperature at positions on the surfaces being in contact with the pouch foil; and a control unit controlling heating temperature of the plurality of sub-heating units on the basis of the temperature sensed by the temperature sensing units.

An automatic control unit for field vulcanizing press is provided. The control unit helps to monitor and control all three essential vulcanizing parameters viz. temperature, pressure and time, either locally or through remote access.

A video recording unit is also provided to record entire splicing operation and also there is option for online video streaming facility and it will help to monitor the entire splicing operation from a remote-control station.

A storage bag comprising a floor, the floor having four corners and edges, the four corners defining a planar surface; a pair of opposing triangular interstitial regions, each triangular interstitial region having a vertex, two sides, and a base, the base of the triangle co-linear with one edge of the floor; a gusset, the gusset bisecting the floor region and both opposing interstitial regions, the gusset co-linear with the vertex of both of triangular interstitial regions; a pair of opposing body regions, the lower edge of each opposing body regions co-linear with two corners of the floor region; and, an opening, the corners of the opening forming an imaginary plane, wherein the planar surface formed by the corners of the floor region and the imaginary plane formed by the opening of the body region are in parallel planes after the storage bag is opened for use.

An imaging window of an imaging catheter includes a first imaging window section and a second imaging window section. The first imaging window section has a finite length and is formed from a first material having a flexural modulus. The second imaging window section has a finite length and is formed from a second material having a flexural modulus. The flexural modulus of the first material is different than the flexural modulus of the second material.

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.
