A method of calibrating a three-dimensional measurement system having a plurality of cameras and at least one projector is provided. The method includes performing a full calibration for each camera/projector pair where the full calibration generates at least two sets of correction matrices. Subsequently, an updated calibration is performed for each camera/projector pair. The updated calibration changes less than all of the sets of correction matrices.

[PROBLEM TO BE SOLVED]

To provide a method for readily forming an easily separable portion having an adhesive strength that is required as a package bag on packaging film, a package bag having an easily separable portion formed by this method, and a filling-packing machine utilizing this method.

[SOLUTION]

A method forming an easily separable portion in packaging film by interposing at least two packaging films between a horn emitting ultrasonic waves and an anvil oppositely disposed to the horn, and vibrating the packaging films by the ultrasonic waves, in which a vibratable layer is provided on the packaging film in at least one of the horn side and the anvil side.

The present disclosure relates to methods for making elastomeric laminates that may be used as components of absorbent articles. The elastomeric laminates may include a first substrate, a second substrate, and an elastic material located between the first and second substrates. During assembly of an elastomeric laminate, a beam is rotated to unwind the elastic strands from the beam, wherein the strands may include a spin finish. First bonds are applied to bond discrete lengths of the stretched elastic strands with and between the first substrate and the second substrate, wherein the discrete first bonds are arranged intermittently along the machine direction. In addition, second bonds are applied between consecutive first bonds to bond the first and second substrates directly to each other, wherein the second bonds extend in the machine direction and may be separated from each other in a cross direction by at least one elastic strand.

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 welding station for an installation for manufacturing packages with pads, the welding station including a plurality of longitudinal welding heads. Each welding head is configured to weld to one another two superposed sheets as said sheets advance in a first direction and may include a welder to apply heat on an action area. Each welding head has a main body, a first traction belt wound in the main body and a second traction belt wound to said main body, parallel to the first traction belt and separated from the first traction belt by a separation gap in a second direction which is transverse to the first direction. The action area is arranged in said separation gap, between both traction belts. Each of the longitudinal welding heads is configured to be able to be moved along the second direction.

A resin film-laminated metal sheet includes a metal sheet and thermoplastic resin films that are fused to both surfaces of the metal sheet, the metal sheet is a steel sheet having a thickness of 0.08 mm or more or an aluminum sheet having a thickness of 0.15 mm or more, and, when a surface of the thermoplastic resin film opposite to a surface that is fused to the metal sheet is defined as a first surface, the surface tension on the first surface in at least one of the thermoplastic resin films is 50 mN/m or less, the surface tension on the surface that is fused to the metal sheet is 36 mN/m or more, and the amount of a wax attached to the first surface is more than 0 mg/m.sup.2 and 5.00 mg/m.sup.2 or less.

A container blank having an article handling feature for handling the container blank as well as the flexible packages made therefrom during manufacture, and method of making flexible packages using such a feature are described herein. Also described herein is an array of flexible packages containing a common article handling feature provided by such a method.

An edge-banding apparatus is provided and configured to apply an edging strip having a heat activated layer to a substrate or work piece. The apparatus uses localized heat generated from a controlled flame from combustible fuel to apply heat to the edging strip to active the heat activated layer.

The methods herein relate to assembling an elastic laminate with a first elastic material and a second elastic material bonded between first and second substrates. During assembly, an elastic laminate may be formed by positioning the first and second substrates in contact with stretched central regions of the first and second elastic materials. The elastic laminates may include two or more bonding regions that may be defined by the various layers or components of the elastic laminate that are laminated or stacked relative to each other. In some configurations, a first plurality of ultrasonic bonds are applied to the elastic laminate to define a first bond density in the first bonding region, and a second plurality of ultrasonic bonds are applied to the elastic laminate to define a second bond density in the second bonding region, wherein the second bond density is not equal to the first bond density.

A joining apparatus includes a fusing mechanism part that joins two thermoplastic sheet-like materials by fusing, a sticking mechanism part that sticks an adhesive tape along a joined portion of the sheet-like materials, a workbench having a placement surface on which the fusing mechanism part and the sticking mechanism part are disposed side by side, the placement surface allowing the sheet-like materials in an unfolded state to be placed thereon, and a guide that allows an end portion to be joined of one of the sheet-like materials and an end portion to be joined of the other sheet-like material to overlap each other while aligned along a plane intersecting the placement surface, each of the end portions to be joined of the sheet-like materials being placed on the placement surface, and to feed the overlapping end portions to be joined. The fusing mechanism part fuses and joins the end portions.
