The present disclosure can provide for an ultrasonic welding method for a pair of workpieces. The method can include first pressing an ultrasonic welding stack against a first workpiece in the pair so that the first workpiece comes into contact with a second workpiece in the pair. The method can then provide for initiating a weld phase by outputting energy from the ultrasonic welding stack to the first workpiece. The method can provide for monitoring, with at least one sensor, a sensed parameter. The sensed parameter can be, for example, weld force and/or weld force rate of change. The method can provide for determining whether the sensed parameter has reached a predetermined level. Based on determining that the sensed parameter has reached the predetermined level, the method can provide for ending the weld phase.

An equipment for manufacturing trampoline includes a rack, a rotation seat, a supporting platform, a plurality of fixing members, a driving member, a driving assembly, and at least one welding device. The rotation seat has a bearing rotatable with respect to the rack. The supporting platform is connected to the bearing. The fixing members are detachably disposed on the supporting platform. The driving member surrounds the supporting platform and is linked-up with the supporting platform. The driving assembly is connected to the driving member.

In one aspect there is provided a tool arrangement for manufacture of a furniture product including a building element, such as a building panel. A tool configuration is configured to be displaced, such as linearly displaced, along a primary axis. The tool configuration includes a drilling device including a drill configured to form an insertion groove in a surface of the building element by means of axial displacement along a longitudinal centre axis of the drill in a direction towards the building element. The tool configuration further includes a dispenser device configured to dispense adhesive means into the insertion groove and an inserter device configured to arrange a locking means in the insertion groove. The longitudinal axis of the rotatable tool is preferably arranged at an acute angle to the primary axis and/or to the surface.

A method for optimizing a welding process to produce a weld joint having a predetermined strength includes measuring a plurality of melt layer thicknesses of weld joints for a plurality of sample assemblies formed by the welding process, measuring a plurality failure loads of weld joints for the plurality of sample assemblies, each of the measured plurality of failures loads being associated with one of the measured plurality of melt layer thicknesses, selecting a first failure load from the plurality of measured failure loads responsive to determining that the first failure load corresponds to a predetermined weld strength, and selecting a first melt layer thickness from the plurality of measured melt layer thicknesses that is associated with the selected first measured failure load.

A hole cutter/punch arrangement that can be changed over quickly to a different hole cutter or punch or slitter, or can instead be converted to a sealer in manufacture of items from plastic film. A reciprocating drive such as an air cylinder is coupled to a transverse mount or holder, of a T-shaped profile and the punches and sealers each have a mounting shoe with a transverse T-profile channel to slide onto the mount where a detent holds the shoe releasably in place. A triple-tree arrangement of a center drive post and left and right guide posts connects to the transverse holder.
