A device for separating a gummed paper and a lining paper of a double-sided tape is provided. In an example, the device includes a housing, a first rotating structure and a second rotating structure which are provided within the housing and a control part. A chamber for accommodating a double-sided tape coil is provided in the housing. The control part fits the chamber, and the double-sided tape coil is rotatable around the control part. The housing is provided with a sliding groove for accommodating the first rotating structure. When the first rotating structure abuts against the second rotating structure, the first rotating structure is positioned in a first limiting part of the sliding groove.

The apparatus for combining tobacco sheets comprises a first shaft for carrying a first bobbin of tobacco sheet and a second shaft for carrying a second bobbin of tobacco sheet. The apparatus also comprises a splicing unit for combining an end portion of tobacco sheet from the first bobbin to a head portion of tobacco sheet from the second bobbin. The splicing unit comprises a cutting device for cutting the tobacco sheets such as to provide complementary cuts to the tobacco sheets from the first bobbin and from the second bobbin, a dispensing device for dispensing water to at least one of the tobacco sheets, and a combining device for applying force onto the tobacco sheets thereby producing a spliced tobacco sheet.

A roll changing apparatus, a winding device, and a gluing device are disclosed in the present application. The roll changing apparatus includes an unwinding assembly including a first unwinding mechanism and a second unwinding mechanism; and a roll changing assembly including a first adsorption mechanism, a second adsorption mechanism, and a cutting mechanism. The cutting mechanism is used to cut off a first material strip between the second adsorption mechanism and a first adsorption area or a second material strip between the second adsorption mechanism and a second adsorption area.

In a bagmaking-and-packaging apparatus, when switching from bagmaking using a first film to bagmaking using a second film, a first impulse sealer interconnects an end-of-bagmaking film of the first film and a starting end scrap of the second film to form a first interconnected film. A second impulse sealer interconnects a third part on a starting end side of the first F1 and a fourth part of the second film to form a second interconnected film.

A method and system for joining strips of battery grid comprises feeding a first strip of battery grid into a processing station at a predetermined feed rate, and progressively increasing the path length of the first strip until a target path length is reached. When the end of the first strip is reached, the path length of the first strip is progressively decreased while holding the end of the first strip. The rate of decrease allows the first strip to continue to be delivered into the processing station at the predetermined feed rate. A second strip is advanced from a second feed supply to a position adjacent the end of the first strip. The adjacent ends are joined by laser welding. The decreasing of the path length is stopped, and the second strip of battery grid is fed into the processing station at the predetermined feed rate.

An electrode connecting device for connecting an end of a preceding sheet to an end of a succeeding sheet includes: an arrangement member provided with an arrangement part on which the end of the preceding sheet is located adjacent to or overlapping with the end of the succeeding sheet; and a guide member having a guide bar which is provided movable between a support position to support a side portion of the preceding sheet and a side portion of the succeeding sheet during connecting of the end of the preceding sheet to the end of the succeeding sheet and a retreat position not to interfere with movements of the preceding sheet and the succeeding sheet.

The present application relates to a roll replacing device and a tab welding apparatus. The roll replacing device includes an unwinding mechanism, a first fixing mechanism, a second fixing mechanism, a cutting mechanism, and a strip connection mechanism; wherein the first fixing mechanism is capable of following a sliding bracket to move along a first direction until a spare material strip fixed by the first fixing mechanism and a working material strip fixed by the second fixing mechanism are aligned at a strip connection station, and allows the strip connection mechanism to connect the working material strip and the spare material strip which are aligned at the strip connection station.

A method is presented for providing a continuous web to an absorbent article manufacturing line. The method includes conveying a first roll of material through a splice box. The method also includes providing a second roll of the material extending into the splice box. The method also includes sensing upcoming expiration of the first roll of material. The method also includes using a first and second vacuum to hold a respective first portion of the first roll and a second portion of the second roll against first and second components of a thermal welding apparatus. The method also includes forming a thermal weld at the splice location between the first and second portions. The method also includes cutting the first roll of material upstream of the thermal weld. The method also includes conveying the second roll of material through the splice box without stoppage of the absorbent article manufacturing line.

A method for joining together two webs includes: overlapping a head portion of the second web on a tail portion of the first web, jointly cutting the head portion of the second web and the tail portion of the first web along a cutting line, so as to form on the first web and on the second web respective front edges offset from each other, and applying a first adhesive splicing tape between a head end of the second web and a tail end of the first web and at the same time aligning frontally with each other the front edges of the first and the second webs.

There is provided a sealing material supply device that continuously supplies a sealing material to an uncoated portion on an edge portion of a current collector on which an electrode is coated, the sealing material supply device including a pair of main body portions disposed so as to sandwich an old sealing material and a new sealing material, a welding portion provided in each of the main body portions, the welding portion being configured to weld the old sealing material and the new sealing material to each other, and a half-cut portion provided in each of the main body portions, the half-cut portion being configured to cut off a surplus portion of the old sealing material and the new sealing material.
