Each of the side seals (4) includes a seal edge portion (41) where the edge portion (3F) of the outer cover (3) in the front body portion F and the edge portion of the outer cover (3) in the back body portion R are bonded to each other by a continuous linear fusion-bonded portion (40) extending in a longitudinal direction of the side seal (4). In a cross-section orthogonal to a direction in which the side seal (4) extends, the fusion-bonded portion (40) includes a narrow section (4F) which is formed at a middle portion thereof in the thickness direction Q and of which a width W along the inner-to-outer direction P is small. The narrow section (4F) includes broad sections (4A, 4B) which are provided on both sides of the narrow section (4F) in the thickness direction Q and of which the width W is larger than the width of the narrow section (4F).

The inventive semi-finished product for a filter, particularly an air filter, comprises a filter medium, wherein said filter medium comprises a nonwoven having fibrous structure produced in a melt-spinning process and at least partially arranged in pleated layers.

A tool for fixing a protective textile sleeve about an elongate member contained therein, and method of use thereof is provided. The tool includes a clamp assembly having opposed clamp members. Each of the clamp members has a clamp surface for abutting the textile sleeve. Each of the clamp surfaces includes a plurality of heating members operably connected to a source of power. The heating members within each clamping surface are supported for independent radial movement relative to one another in response to engagement with an outer surface of the textile sleeve to allow the clamp surfaces to automatically conform to the arcuate shape of the sleeve and elongate member being clamped therebetween.

A system and method for joining a plurality of paper material together with ultrasonic welding to form a hang tab for displaying products, such as, e.g., in a retail environment, without the use of an adhesive, such as, e.g., glue, and/or printing dye or ink. The paper hang tab may replace plastic hooks or tabs, which may be more environmentally beneficial. Two or more pieces of paper may be inserted into a gap between a sonotrode and an anvil of an ultrasonic joining device. A joining force from an actuator may be applied to secure the pieces of paper, and the sonotrode may oscillate a high-frequency. Adequate compaction of the pieces of paper is produced in addition to a high development of heat from friction generated in the micro-region of the thermoplastic coating. Melting of thermoplastic coating then forms a physical connection between the pieces of paper, effectively fusing them together.

A rotary device for welding a continuous web includes a rotary element, support elements for supporting the web, supported by the rotary element, and a plurality of welding units for welding the web. Each welding unit passes from a non-operating position to an operating position and vice versa, and includes a first movement device for commanding a relative rotation of an anvil element relative to a welding tip and a second movement device for moving the anvil element relative to the welding tip such that a contact surface of the anvil element and a contact surface of the welding tip make contact with a portion of the web in a zone between them, and vice versa. First and second drive mechanisms drive the first and second movement devices. The first and second drive mechanisms are configured to vary a positioning of the welding tip relative to the axis.

Provided is a bonding method capable of bonding with an inexpensive structure while avoiding an increase in the overall size of the device. The bonding method comprises: an arrangement step for locating a cylindrical body between two sheet-shaped members; a cylindrical body bonding step for applying an ultrasonic wave from the outer surface of a first sheet-shaped member through a horn part and applying heat from the outer surface of a second sheet-shaped member through an anvil part, in a state in which the cylindrical body is arranged between the two sheet-shaped members; and a shoulder part bonding step for directly bonding, through a pair of heating parts, the two sheet-shaped members to each other while the two sheet-shaped members are interposed between the pair of heating parts.

A method for producing a fencing material including the steps of: providing a border material having an interior surface; providing a mesh material having a front and a back; treating the interior surface of the border material to produce a tacky border material surface; placing a portion of the front and/or the back of the mesh material against the tacky border material surface; pressing the tacky border material surface and the mesh material together; and thermally bonding at least some portion of the front and the back of the mesh material with the interior surface of the border material. The border material being a polyvinyl chloride, the mesh being a polyvinyl chloride material and/or a vinyl coated material.

A bag (100) for packaging fruit and vegetable products (2) having a casing (103) for housing the products to be packaged and at least one first band (104) and one second band (105), each arranged on the outer face of the casing so as to seal the casing, the first band (104) being joined to the casing only at its ends (104a, 104b) forming a handle (106) and the second band (105) joined along the length thereof to the associated face of the casing, forming a stable bottom (105c).

A head seal device of a bag making apparatus includes a pair of seal units configured to face each other in a facing direction. Each of the seal units includes a heat seal member and a heater. The heat seal device includes an adjustment unit configured to move the first seal unit in a width direction of continuous sheet panels, and to move the second seal unit in the width direction of the sheet panels in accordance with movement of the first seal unit in the width direction.

A system and method for controlling the speed of both a continuous web and a bonding apparatus is provided in order to effectuate stronger bonds in the web. The bonding system includes a velocity changing device for increasing and decreasing a velocity of the web in a machine direction, an anvil and a corresponding ultrasonic horn that interact to form ultrasonic bonds on the web, and an anvil actuator configured to control a movement of the anvil. A control system is also included in the bonding system for controlling operation of the anvil actuator the velocity changing device, with the control system programmed to decrease a moving velocity of the web from a feed velocity to a bonding velocity as the web passes between the anvil and the ultrasonic horn and control movement of the anvil to synchronize the movement of the anvil with the moving velocity of the web.
