A portable table top welder for welding plastic material webs, the portable table top welder including a frame including a carrier housing and a support arm at which a welding device is arranged; at least one transport roller including a rotatable transport roller axle and at least one contact pressure roller that is rotatably supported at the carrier housing, wherein a weight is arranged at an eccentrical element which is rotatably connected at one side by a concentrically supported eccentrical element axle at the carrier housing and rotatably connected at another side by an eccentrically supported contact pressure roller axle at the contact pressure roller. The table top welder handles and transports easily and can be mounted on a table or on another carrier structure in a disengageable manner.

A friction welding apparatus is provided, which includes a tool, a rotary driver, a linear driver, and a control device. The control device controls the linear driver and the rotary driver so that the tool is rotated while a tip-end part thereof is pressed against a to-be-joined part of a to-be-joined object to increase a temperature of the to-be-joined part at or above an A1 transformation point, the tip-end part of the tool reaches a given first position so that a softened second member sticks into a softened first member, and the tool is drawn out from the to-be-joined part while the tool is rotated.

A method and a connecting element for joining two components, at least one of which is made of a fiber-reinforced composite, are proposed.

Disclosed in an assembly for forming bags, having a belt drive for feeding a film at a film speed to a former shoulder to form a tubular film, a set of jaws movable at a jaw speed to engage and seal a tubular film to form a closed bag, and a sensor assembly to provide a volume signal indicative of a volume of the closed bag, wherein the controller is configured to adjust at least one of the film speed and the jaw speed in response to the volume signal.

A system for checking a package body with an image is capable of automatically judging good or bad product of manufactured package bodies and automatically performing change of production conditions in a filling and packaging machine, and includes a filling and packaging machine, an image data judgement system, a storage device and an image data analysis system, wherein the image data judgement system is provided with an imaging device for shooting a package body, a storage unit for storing judgement condition on good or bad package body, a judgement unit for judging good or bad package body and an image data transmission unit for transmitting the image data shot by the imaging device to the storage device, and the image data analysis system is provided with an image data acquisition unit for acquiring image data and so on judged as a bad product in the judgement unit from the storage device.

A process for producing a surface covering with an embossed printed surface is described. A substrate (16) is continuously moved through a production line, and this substrate (16) is first provided, in a printing equipment (12), with a printed pattern and thereafter, in an embossing equipment (14), with an embossed pattern, which is registered with the printed pattern. The printing equipment (12) produces the printed pattern in-line with the production of the embossed pattern. During printing in the printing equipment (12), the printed pattern is stretched or compressed, dynamically responsive to indicators of misalignments between the printed pattern and the embossed pattern, so as to correct or prevent the misalignments. A production line for carrying out this process is also proposed.

A system for, and method making and repairing a fiber-reinforced component including bonding a first thermoplastic matrix possessing reinforcing fibers distributed therein to a second composite member possessing a thermoplastic matrix with reinforcing fibers distributed therein; and metals and more particularly a method and apparatuses for joining fiber reinforced thermoplastics utilizing a combination of heat, force and rotational force.

A device and a method are provided for setting a press-in element into a workpiece at a predetermined location. The device includes main body; a fixing unit, which is attached to the main body and which is designed to fix the workpiece; and a processing unit, which is attached to the main body and includes: a boring unit, which is designed to create a bore in the workpiece fixed by the fixing unit; and a pressing unit, which is designed to press a press-in element into the bore. The method fixes the workpiece; creates a bore in the workpiece; positions a press-in element over the bore; and presses the press-in element into the bore, wherein a single device is used to carry out the method.

A system and method for producing a disposable undergarment, with the lateral edges of the undergarment bonded by means of an ultrasonic horn. When a blank is formed for an individual undergarment, the lateral edges of opposing edges of the blank will form the seam. When the edges are sealed together, a seam is formed. The individual undergarments may be later separated along the seams.
