Abstract: A method for producing a piezoelectric actuator (8) with a multilayer structure of layers of a piezoelectric sheet (3, 4), and with inner electrodes disposed between them, is proposed, in which the individual layers are formed of two continuous strands (3, 4) of the piezoelectric sheet, and the two strands (3, 4) are wound over one another in the form of a double helix to form a hollow-cylindrical stack, thereby enclosing the inner electrode between them. The two strands (3, 5) are preferably guided over deflection rollers (5, 6, 7) in such a way that the overlays of the two strands (3, 4) on the already-wound stack are offset from one another by a predetermined angular amount.

An adhesive layer is disposed over and secured to the outer surface of the roll core base. A cover is formed of a thermoplastic material, the cover having a thermoset resin infused reinforcement fiber layer, the fiber layer circumferentially surrounding and secured to the adhesive layer, whereby the cover is bound to the rotatable roll core base.

Abstract: One carpet seaming tool has an elongate, generally straight handle having on one end thereof a U-shaped bracket having spaced, parallel legs. Secured intermediate its ends in a pair of registering openings in the legs of the bracket is an elongate shaft having rotatably mounted coaxially thereon three rollers, one positioned between the two legs of the bracket and the other two positioned adjacent opposite ends of the bracket. Each roller is generally spirally shaped in configuration, having a spirally shaped outer circumferential surface disposed to have rolling engagement with the surfaces of two carpet sections that are being seamed together. In an alternative form, the handle is curved slightly intermediate its ends, and in addition to having the three spirally shaped rollers on the one end thereof, it has also mounted on its opposite end a U-shaped bracket with an elongate shaft secured intermediate its ends in registering openings in the legs of the bracket.
