A production method of a long member including a large number of carbon nanotubes includes the steps of: (1) drawing the carbon nanotubes gradually from a first array to obtain a first web 10a; (2) bringing the first web 10a partially into contact with a first holder 12a to hold the first web 10a on the first holder 12a; (3) drawing the carbon nanotubes gradually from a second array to obtain a second web 10b; (4) bringing the second web 10b partially into contact with a second holder 12b to hold the second web 10b on the second holder 12b; and (5) placing a portion of the first web 10a and a portion of the second web 10b on each other to form a joint, the portions of the first and second webs 10a and 10b being in the vicinity of the first and second holders 12a and 12b, respectively, and being placed on each other such that width directions of the first and second webs 10a and 10b are substantially the same.

A fabric, in particular a press felt, is provided for use in a press section of a machine for producing a fiber web such as a paper, cardboard, or tissue web. The fabric is formed of multiple strips which are arranged adjacent one another and extend substantially parallel to one another in a machine direction. The strips together form a width of the fabric in the machine transverse direction. Each strip is designed as a double-layered sheet material. Strips arranged adjacently in respective pairs are connected by way of a connecting strip. A part of the width of each of the connecting strips extends in the machine transverse direction into the two adjacent strips. The strips are connected to the connecting strips.

In a joining jig for disposing a sheet-shaped adherend on one surface side of a sheet-shaped material, folding back the adherend in an end edge portion of the sheet-shaped material, and causing adhesion of an end edge portion of the adherend on the other surface side of the sheet-shaped material, by a tip portion of an attachment piece pivoting in the end edge portion of a placement surface of a placement base, the attachment piece is switchable between a deployment position where an attachment surface to which the adherend is attached is deployed outside the end edge portion of the placement surface of the placement base and a facing position where the attachment surface faces the end edge portion of the placement surface.

The invention relates to a method for the ultrasonic welding of a strip consisting of a plastic material for the production of cigarette products, in which method the strip has two free ends which are heated in a connection region by means of ultrasound and joined together to form a closed strip. Ultrasound at a frequency of more than 22 kHz is used.

The invention relates to a device and a method for connecting finite webs of material for the energy cell producing industry, wherein the device comprises a holding device adapted to hold the new web of material by means of negative pressure in the second guide section, as well as a backing element and a cutting element, downstream in the conveying direction of the holding device. The backing element and the cutting element are adapted to cut the stationary new web of material to produce a new leading end of the new web of material. The device also comprises an applicator for applying an adhesive strip to the new leading end of the new web of material and a ram and a cutting device, wherein the cutting device is adapted to cut the stationary running-out web of material to produce a new trailing end of the running-out web of material. The ram is adapted to press the trailing web end of the running-out web of material onto the adhesive strip and against the applicator in order to connect the new leading end of the new web of material to the new trailing end of the running-out web of material.
