Laminate web comprising an apertured layer and method for manufacturing thereof

A laminate web comprising a first web, a second web joined to the first web at a plurality of discrete bond sites; and a third material disposed between at least a portion of the first and second nonwovens. The third material is apertured in regions adjacent the bond sites, such that the first and second nonwoven webs are joined through the apertures. In one embodiment an apertured laminate web is disclosed, having a first extensible web having a first elongation to break, and a second extensible web joined to the first extensible web at a plurality of bond sites, the second extensible web having elongation to break. A third web material is disposed between the first and second nonwovens, the third web material having a third elongation to break which is less than both of the first or second elongations to break. In a further embodiment, an apertured laminate web is disclosed, having first and second extensible webs being joined at a plurality of discrete bond sites and a third material disposed between the first and second nonwoven webs. The first and second nonwoven webs are in fluid communication via the apertures and have distinct regions being differentiated by at least one property selected from the group consisting of basis weight, fiber orientation, thickness, and density.

Optical connector cleaning tool

An optical connector clearing tool (1) includes a holder (2), cleaner (5), and cap (6). The holder (2) includes, e.g., a cylindrical slider (10), a cylindrical body (12) installed to be rotatable and movable in the axial direction with respect to the slider (10), and a slider return spring (13) which biases the body (12) forward to return the slider (10) to the initial position. The slider (10) has a pair of elastic pieces (16) having guide projections (17). In the outer circumferential surface of the body (12), spiral grooves (25, 26) with which the guide projections (17) engage are formed within the angular range of 360°. When the slider (10) moves forward, the body (12) rotates by the cam action of the guide projections (17) and spiral grooves (25, 26). The cleaner (5) includes, e.g., a cleaning thread (41) accommodated in a rotary pod (40), a supply reel (42), a take-up reel (43), and a cleaning pin (44), and is connected to the body (12). The rotary pod (40) and cleaning pin (44) rotate together with the body (12), and the cleaning thread (41) supplied to the distal end face of the cleaning pin (44) cleans the connection surface of an optical connector. The cleaning thread (41) is supplied from the supply reel (42) and taken up to the take-up reel (43) by being given tension by the rotation of the cleaner (5).
