Abstract:
A transportation device for transferring bristles from one location to another location may comprise a tube system and a baffle plate comprising conically shaped vents. The baffle plate may be arranged at one end of the tube system in order to stop the movement of the bristles transported inside the tube system using airflow. Such a transportation system may be part of a device for automated production of brushes, in particular toothbrushes. A plurality of bristles can be transferred by such transportation system in order to be arranged in a pre-defined bristle pattern corresponding to a bristle field of a brush, in particular a tooth brush.
Abstract:
The present disclosure relates to methods and apparatuses for assembling absorbent articles, and more particularly, methods and apparatuses for imparting a line of weakness into one or more layers of an advancing substrate. The advancing substrate may be a belt assembly including an outer layer, an inner layer, and one or more elastic strands disposed between the outer layer and the inner layer. The belt assembly may be rotated on a process member about a longitudinal axis of rotation. The process member may advance the belt assembly to a first laser source. The first laser source imparts a line of weakness into the belt assembly. A trim removal member may be used to separate the line of weakness forming a trim portion and a separation edge.
Abstract:
A method for providing bristles for automated production of brushes, in particular toothbrushes or parts thereof may comprise providing a plurality of bristles in a storage container, applying oil to at least a part of the plurality of bristles in the storage container, separating a bristle tuft from the storage and transporting the bristle tuft in a tube using an airflow. Thereby a plurality of bristles tufts can be transferred to a providing unit, in which the bristles tufts are arranged in a pre-defined tuft pattern and may be over-molded by injection molding in order to form at least a brush head. A device suitable to perform such a method comprises at least an immersion unit to apply oil to bristles and an airflow-using transportation unit.
Abstract:
The present application is concerned with a mold insert defining at least one filament cavity and having a stack of at least a first insert plate and a second insert plate, wherein the first plate has a front face that closely abuts a front face of the second insert plate, at least a portion of the at least one filament cavity is provided in at least one of the front faces of the first insert plate or second insert plate such that the filament cavity is open at a top surface of the mold insert but does not extend to a bottom surface of the mold insert, a venting cavity is provided in the same front face of the insert plate in which the portion of the at least one filament cavity is provided, which venting cavity is in air-conducting connection with the blind-hole end of the filament cavity, and the venting cavity has a depth in a direction essentially perpendicular to the front face of the respective first or second insert plate in which the venting cavity is provided that is the in the range of between 1 µm and 20 µm, in particular of between 2 µm and 10 µm. The present application is also concerned with a method of making such a mold insert and a mold machine comprising such a mold insert.
Abstract:
The present disclosure relates to methods and apparatuses for imparting a first line of weakness and a second line of weakness into one or more layers of an advancing substrate, such as a belt assembly. The first line of weakness is coincident with the second line of weakness. The advancing substrate may be a belt assembly including an outer layer, an inner layer, and one or more elastic strands disposed between the outer layer and the inner layer. A first surface of the belt assembly may be acted on by a first laser beam that operatively engages a first scan head and a second surface of the belt assembly may be acted on by a second laser beam that operatively engages a second scan head. A trim removal member may be used to separate the first and second lines of weakness forming a trim portion and a separation edge.
Abstract:
The present disclosure relates to methods and apparatuses for assembling absorbent articles, and more particularly, methods and apparatuses for imparting a line of weakness into one or more layers of an advancing substrate and separating the substrate along the line of weakness to form a separation edge. The advancing substrate may be a belt assembly including an outer layer, an inner layer, and one or more elastic strands disposed between the outer layer and the inner layer. The belt assembly may be rotated on a process member about a longitudinal axis of rotation. The process member may advance the belt assembly to one or more ultra short pulse laser sources. The ultra short pulse laser source imparts a line of weakness into the belt assembly. A trim removal member may be used to separate the line of weakness forming a trim portion and a separation edge.
Abstract:
The rotary anvils herein may be used in combination with a tool member to perform various types of manufacturing operations, such as cutting, bonding, and embossing. The anvil roll (100) includes a cylindrically-shaped outer circumferential surface (102) and is adapted to rotate about a first axis of rotation (104). More particularly, the anvil roll (100) includes a body (110) formed from a first material (118), such as a metallic material. The body also includes grooves (130) in the outer circumferential surface (102), and abrasion resistant material (120) is fused to the body to fill the grooves (130) to form strips (112). During operation, a tool member (134) is positioned to contact the strips (112) of abrasion resistant material (120).

The present disclosure relates to methods and apparatuses for assembling absorbent articles, and more particularly, methods and apparatuses for imparting a line of perforation into one or more layers of an advancing substrate and separating the substrate along the line of perforation to form a separation edge. The advancing substrate may be a belt assembly including an outer layer, an inner layer, and one or more elastic strands disposed between the outer layer and the inner layer. The belt assembly may be rotated on a process member about a longitudinal axis of rotation. The process member may advance the belt assembly to one or more ultra short pulse laser sources. The ultra short pulse laser source imparts a line of perforation into the belt assembly. A trim removal member may be used to separate the line of perforation forming a trim portion and a separation edge.
