A vibration measurement device measures vibration of at least one of the first sealing member and the second sealing member. A determination device determines quality of the sealing process according to a measurement result of the vibration measurement device from before the first sealing member and the second sealing member reach the closed position to after the first sealing member and the second sealing member reach the closed position. The sealing drive unit causes relative movement between the first sealing member and the second sealing member from an open position at a moving speed determined according to a type of the bag, to place the first sealing member and the second sealing member in the closed position.

A method of producing flexible polypropylene fabric bags with heat fused seams comprising providing fabric pieces, wherein each fabric piece has a coated side and an uncoated side; positioning fabric pieces so that a coated side of one fabric piece faces a coated side of another fabric piece; selecting an area of fabric to be joined for forming a seam or joint; applying heat to the area to be joined that is less than the melting point of the fabrics, for forming one or more seams or joints and wherein the heat fused seams or joints of a resulting polypropylene bag retains at least 85% of the fabric strength without using sewing machines.

A composite laminate for connection to at least one attachment component in a load-introduction joint, said composite laminate comprising an opening that is adapted to receive a load-introduction component of said load-introduction joint, wherein a prefailure indication element is provided in the region of said opening, said prefailure indication element being modifiable by said load-introduction component in a prefailure mode of said load-introduction joint for indication of an impending function-affecting failure of said composite laminate. The invention is further related to a corresponding load-introduction component.

The invention relates to a method for producing a test body (30) for mechanically destructively testing a materially bonded joining connection, wherein the method comprises the following steps: providing an areal fiber composite substrate formed from a fiber composite material which has a fiber material and matrix material in which the fiber material is embedded, applying at least one test fabric and an adhesive to a substrate surface of the areal fiber composite substrate, and curing the adhesive, and therefore a materially bonded joining connection is produced between the test fabric and the substrate surface by way of the cured adhesive,
wherein a Dutch-weave fabric and/or a square-mesh fabric is provided as the test fabric.

The present invention relates to a method for producing an adhesive bond, comprising the steps of curing (S101) a light-curing adhesive material by means of light; detecting (S102) a degree of polymerization of the adhesive material; and terminating (S103) the curing at a specified degree of polymerization.

A method includes assembling a sensor subassembly that includes a sensor, a sensor mount, a collar, a sharp, and a sensor cap. The method includes loading a sensor in a sensor mount; dispensing adhesive into a mount channel of the sensor mount; clamping a collar to the sensor mount; and curing the adhesive to fix the collar to the sensor mount. The method can also include inserting a sharp into the sensor mount over the sensor an attaching a sensor cap to the sensor and sensor sharp to provide a sealed sensor subassembly. Methods of assembling an on-body sensor puck assembly and an applicator assembly, and a sensor including a tail, a flag, and a neck that interconnects the tail and the flag and methods of configuring a sensor are also disclosed.

A method of making and testing a wind turbine blade comprises providing a structural member having a web portion and a flange portion, where the flange portion extends away from the web portion and a curvilinear heel is defined between the web and flange portions. 5 A flange extender is integrated with the flange portion, where a first section of the flange extender overlies the flange portion, and a second section of the flange extender extends past the heel and away from the web portion. The flange extender is bonded to the inner surface of a wind turbine blade shell. Non-destructive test (NDT) equipment is used to assess the integrity of the bond by identifying first and second target surfaces of the 10 structural member. The target surfaces are spaced apart by an intermediate region, corresponding to the location of the heel, where it is not possible to positively identify any surface using NDT techniques. Identification of the two target surfaces indicates a good integrity bond in the intermediate region, whereas identification of only one, or neither, of the target surfaces indicates a poor integrity bond. 15

A method of forming a structural web for a wind turbine blade comprises providing a web member having a web portion and a flange portion extending away from each other, where 5 a heel of substantially curvilinear form is located between the web portion and the flange portion. A planar flange extender comprising a cured composite material is arranged together with the web member with the flange extender positioned adjacent to the flange portion so that a portion of the flange extender projects past the heel and away from the web portion. The flange extender is integrated with the web member in a resin matrix, or 10 with an adhesive, to form the structural web. A structural web and a wind turbine blade comprising the web is disclosed.

A method for quality assessment of a sealing section of a package, wherein the package includes at least a robustness layer and a plastic layer. The sealing section is formed by holding a first section and a second section of the package against each other while providing heat such that the plastic layer of the first and second section melt and thereby provide for that the first and second section adhere to each other. The method includes capturing image data depicting the sealing section using a camera, identifying a reference line in the image data, identifying a sealing section boundary line in the image data, determining a sealing section assessment feature set based on the reference line and the sealing section boundary line, and comparing the sealing section assessment feature set with a reference feature set.
