A joining pin (3.2) with which two parts (1 and 2) made from a porous material, particularly wood or a wood-like material, are to be joined together, is anchored in the porous material at predetermined anchoring points (31, 33). For this purpose, a bore (4.2) with a closed inner end (41) is made in the parts (1 and 2). The shape of this bore (4.2) is so matched to the joining pin (3.2) that it can be introduced substantially without force expenditure into the bore and is positionable in a first position. At least one predetermined anchoring point (31, 33) between the joining pin (3.2) and the wall of the bore (4.2) is formed when pressure is built up by pressing the joining pin (3.2) with a pressing force (F) more deeply into the bore to a second position. Energy is supplied in a planned manner to the joining pin (3.2) so that at the predetermined anchoring points (31, 33) the thermoplastic material of the joining pin (3.2) is plasticized. The locally plasticized plastic material is pressed by the local pressure into the porous material of the parts and forms local, macroscopic anchors (10, 20). The joining pin (3.2) is, e.g., made entirely from a thermoplastic material and the energy for plasticizing is supplied thereto by ultrasonic vibration.

A connector for interconnecting two building members together. The connector, in one embodiment, includes first and second plates secured together. Each plate includes one or more elongated slots wherein the elongated slots of one plate are oriented at an angle of approximately 90° with respect to the slots formed in the other plate. Fasteners extend through the slots in the plates and connect the plates of the connector to two building members such as a horizontal building member and a vertical building member. Once connected, one of the building members is free to move with respect to the other building member while the connector is connected to the two building members. In another embodiment, the connector is slidable within a track. In this embodiment, a portion of the connector extends from the track and connects to one of the building members while the track connects to the other one of the building members.

The present invention provides an improved apparatus for forming a fibrous pad for absorbent products with improved density control. Fibers entrained in a high speed air flow are deposited onto the foraminous surface of a spaced, three-dimensional pad-forming pocket. The fine foraminous pad forming screen is supported on its periphery by two top plates, a coarse forming screen, two subplates and end rails which incorporate a device to hold the pad forming screen. A gas flow regulating system consisting of precisely placed cross directional fixed and adjustable airflow control louvers controls the air flow direction and reduces spill over and turbulence during the pad formation and especially during the transition of the forming pocket into and out of the air stream as the rotary former shell rotates through the filling position. Additional control of density and fiber placement is gained through the use of additional gas control innovations including a tapering the pocket ends such that the airflow is streamlined especially during pocket transition through forming sections.
