Method and application unit (3) for applying a sound-absorbing material (2) to an inner cavity of a pneumatic tyre (1). The following steps are provided: eliminating an excess end (5) of a strip (4) of sound-absorbing material (2); progressively separating a protective lining (7) from an adhesive layer (6) of the strip (4) as the strip (4) of sound-absorbing material (2) is applied to the inner cavity of the tyre; implementing by means of the strip (4) a separation opening (8) that starts from an opposite side of the protective lining (7) and ends at the protective lining (7) which remains intact, and separating the excess end (5) from the remaining part of the strip (4) of sound-absorbing material (2); and pulling the excess end (5) in relation to the remaining part of the strip such as to separate the protective lining (7) from the strip (4).

A process and an apparatus for making a refastenable side seam of an hygienic absorbent article efficiently, without the need to remove scrap and which allows refastenable side seams to be obtained which are ergonomic, aesthetically pleasing, easily identifiable by the user and such that they do not reduce the wearability of the article. The disclosure also relates to a hygienic absorbent article provided with at least one refastenable side seam. The disclosure also relates to a process and an apparatus for carrying out one or more operations on elastic panels usable for making an hygienic absorbent article provided with at least one refastenable side seam.

A solar panel disassembling apparatus according to an embodiment of the present disclosure separates a glass plate of a solar panel and a film layer bonded to the glass plate from each other. The solar panel disassembling apparatus includes a supply module that stands and fixes the solar panel such that a bond line between the glass plate and the film layer is exposed upward and downward and that moves the solar panel in a parallel direction parallel to a bonding surface between the glass plate and the film layer, and a wire-shaped cutting blade that is disposed in front of the solar panel in a movement direction of the solar panel to have a distance from the supply module, is disposed in parallel to the bonding surface, and separates the glass plate and the film layer from each other.

A bundle breaker including first and second platen assemblies mounted above upstream and downstream breaking supports with first and second actuators for moving the platen assemblies toward and away from the breaking supports and a third actuator for moving the downstream breaking support to perform a breaking operation. The first platen assembly and/or the second platen assembly each includes an upper platen assembly and a lower platen assembly supported by the upper platen assembly, the upper platen assembly including an upper platen and a support for the upper platen and the lower platen assembly including a lower platen supported for movement relative to the upper platen in the vertical direction and relative to the upper platen in the longitudinal direction.

Systems and methods are described for controlled crack propagation in a material using ultrasonic waves. A first stress in applied to the material such that the first stress is below a critical point of the material and is insufficient to initiate cracking of the material. A controlled ultrasound wave is then applied to the material causing the total stress applied at a crack tip in the material to exceed the critical point. In some implementations, the controlled cracking is used for wafering of a material.

A bundle breaker has upstream and downstream breaking supports each having an input end and an output end. A first platen is located above the upstream breaking support, and a second platen is located above the downstream breaking support, and each platen has an actuator for moving the respective platen toward and away from the breaking supports to selectively clamp a log between the platens and the breaking supports. A third actuator is configured to apply a shifting force to the downstream breaking support to shift the input end of the downstream breaking support relative to the output end of the upstream breaking support from a first position toward a second position to break the second portion of the log from the first portion of the log. The first actuator and/or the second actuator and/or the third actuator includes at least one servo motor.

A bundle breaker includes upstream and downstream breaking supports, platens over the breaking supports and actuators for moving the platens toward and away from the breaking supports. Each of the platens includes a plurality of air bladders each having a bottom contact surface facing one of the breaking supports. The actuators move the platens to selectively clamp a log between the bottom contact surfaces of the air bladders and the breaking supports. A third actuator shifts an input end of the downstream breaking support relative to an output end of the upstream breaking support from a first position to a second position to break a first portion of the log from a second portion of the log.

A paper straw including a straw assembly, a shortening assembly, a drinking assembly is disclosed. The paper straw includes a cylindrical biodegradable body comprising multiple perforation lines along the top portion of the straw wherein damaged sections of the straw can be removed by ripping or tearing the section off. This allows for using of a same straw even when the top portion is damaged or soggy. This aids in environmental friendliness, as less paper straws have to be used. When it comes time to dispose of the paper straw minimal damage is done to the environment as the paper straw is biodegradable.

After a glass sheet (G) having a scribe line (S) formed thereon is placed on a placement table (10) and positioned so that the scribe line (S) is positioned in a bending stress applying portion (15) of the placement table (10), when the glass sheet (G) is split along the scribe line (S) by applying a bending stress to a formation region of the scribe line (S) by the bending stress applying portion (15), the glass sheet (G) is positioned by laying a resin sheet (9) under the glass sheet (G) on the placement table (10) and aligning one side (G1) of the glass sheet (G) extending in a direction along the scribe line (S) with marks (Ma to Nd) projected onto a protruding portion (9a) of the resin sheet (9) by laser markers (16a to 16d).
