The paper side machine direction yarns are cut at a cutting point. Cutting points form a fasten-off row. Yarns that form seam loops are fastened off in a first fasten-off row and yarns that form an edge of the seam area are fastened off in one or more second fasten-off row. One fasten-off row is situated at the beginning line of the seam area.

The invention provides a biaxially-oriented polypropylene (BOPP) tangle membrane which comprises a core layer, a first surface layer and a second surface layer, wherein the first surface layer is positioned between the core layer and the second surface layer. Material of the core layer comprises, by weight percentage, 10-30% of low molecular weight hydrogenated petroleum resin, 2-4% of antistatic agents, 10-18% of atactic propene polymer (PP), and the balance homopolymerized propene polymer (PP). Material of the first surface layer comprises, by weight percentage, 2-4% of slipping agents, and the balance homopolymerized PP. Material of the second surface layer comprises, by weight percentage, 3-5% of anti-sticking agents, and the balance homopolymerized PP. The degree of crystallinity of the BOPP tangle membrane is lowered, low molecular material having good intermiscibility with the PP is added to the BOPP tangle membrane, the microstructure of the BOPP tangle membrane is more densified, macromolecules are easy to tangled up to achieve preferably tangling force during tangling, and vertical and horizontal mechanical properties are nearly consistent. The BOPP tangle membrane has the advantages of being light in weight, excellent in combination property, capable of achieving high-speed large-scale production and the like. The invention further provides a preparation method of the BOPP tangle membrane.

The invention relates to vehicle pneumatic tires having a tread which, observed in the case of tires mounted on the vehicle, has a profile band (1) arranged on the outside shoulder which is separated from additional profile elements by a circumferential groove (2) which extends in the circumferential direction, wherein a plurality of transverse grooves (3), extending at least substantially parallel to each other, is provided in the shoulder-side profile band (1), which groves consist of a plurality of groove sections (4, 5, 6, 6') extending at angles to each other. The transverse grooves in the outside shoulder region are comprised of three groove sections (4, 5, 6, 6'), wherein the two outer groove sections (4, 6, 6') extend at least substantially in the axial direction and the center groove section (5) connecting said outer groove sections extends to the two outer groove sections (4, 6, 6') each at an obtuse angle (β, β'), which equals 135° at maximum, wherein the outer groove sections (4, 6, 6') each have a groove flank (7, 14), extending at least substantially in the axial direction, and a groove flank (7, 14) comprised of a flank section (7'a, 14'a), extending at least substantially in the axial direction, and a bevel (8, 12), wherein the center groove section (5) is formed from two bevels (9, 10), wherein the bevels (8, 12) in the outer groove sections (4, 5, 6, 6') extend to a depth identified in the axial direction which is a specific value, proportional for said bevels (8, 12), of both or the greatest depth (T) of said groove sections (4, 5, 6, 6'), and wherein the bevels (9, 10) which form the center groove section (5) extend to a depth which at least substantially equals the depth of the bevels (8, 12) of the outer groove sections (4, 6, 6') on the corner regions thereof to the center groove section (5).

The engine pendant for assembling swinging engine with two lifting eye bearings onto frame includes one first locking seat, one second locking seat, one locating sleeve penetrating the lifting eye bearings, one locating sleeve cover, and one fixing rod locked to the second locking seat.
