A hammock assembly is provided and includes a zipper fastening system, a hammock, and a cover. The zipper fastening system includes a first tape section and second tape section corresponding to the first tape section. The hammock includes a hammock body with the first tape section attached to an edge thereof. The cover includes a cover body having the second tape section attached to an edge thereof. The cover is removably attachable to the hammock by connecting the first tape section and the second tape section.

Provided is an aluminum alloy element for a slide fastener, which has improved strength and abrasion resistance. The element for the slide fastener includes a base material of an aluminum alloy having a composition represented by a general formula: Al.sub.aSi.sub.bCu.sub.cMg.sub.dTi.sub.eB.sub.f in which a, b, c, d, e and f each represents % by mass; a is a balance; 0.2b0.8, 0.8c1.8, 0.8d1.8, 0<e0.05, and 0<f0.01; and unavoidable impurity elements may be contained; the aluminum alloy comprising, dispersed therein, precipitates containing at least one element selected from a group consisting of Al, Si, Cu and Mg, the element for the slide fastener comprising a pair of leg portions and a head portion that connects the pair or leg portions and comprises a convex portion and a concave portion for engagement.

A slide fastener tape member includes a tape body and a core string portion disposed at a tape side edge portion of the tape body along a length direction. The core string portion is formed by fixing a string member at the tape side edge portion along the length direction by machine sewing. The string member is fixed linearly such that at least one thread used for machine sewing crosses while contacting an outer peripheral surface of the string member without being pierced by a needle thread of machine sewing. Thus, since the core string portion can be easily provided by fixing the string member to the tape body having desired properties at a later stage, the value-added tape members can be easily manufactured at a relatively low cost.

Elements for a slide fastener are provided, which have high strength and improved abrasion resistance. More particularly, an element for a slide fastener includes as a base material, an aluminum alloy having a composition represented by a general formula: Al.sub.aSi.sub.bCu.sub.cMg.sub.d in which a, b, c and d are expressed in percentage by mass, a denotes a balance, 0.4b0.9, 0.15c0.8, 0.8d2.0, and unavoidable impurity elements may be contained; and the aluminum alloy containing a precipitate containing Mg and Si.

A marking device performs a marking process onto a long object. The marking device includes a driving source and a marking unit that performs a circular motion in accordance with a driving force supplied from the driving source. While the long object is being transferred, marks are applied onto the long object in accordance with the circular motion of the marking unit. An extent of interference by the marking unit to the transfer of the long object is reduced, thus facilitating higher speed transfer of the long object.

An element is configured to be installed together with a tape to form a fastener stringer, and includes: a main body including an upper main body and a lower main body; an installing portion for installing the tape; a head; and a neck connecting the main body and the head, wherein at least one of the upper main body and the lower main body includes a convex portion and a base portion, the convex portion protrudes from the base portion and extends in the left-right direction at an intermediate position in the front-rear direction. An inclined portion inclined downward along the left-right direction is formed on at least one side of the head along the upper-lower direction, and protrusions extending in the front-rear direction are formed on both sides of the convex portion.

An item may be provided with a body that forms an enclosure. The body may have a body portion that opens and closes along a seam. An elongated magnetic fastener may run along the seam. The magnetic fastener may have first and second strips of elastomeric material on opposing sides of the seam. Magnetic interlocking elements may be partially embedded in the first and second elastomeric strips. The fastener may be formed by injecting uncured elastomeric material having unmagnetized magnetic particles into a mold. While in the mold, a magnetic field may be applied to magnetize the magnetic particles and to align the magnetic particles into magnetized structures. After forming the magnetized structures within the elastomeric material, the elastomeric material may be cured. Once removed from the mold, portions of the elastomeric material may be removed to expose the magnetized structures, which may subsequently be shaped into interlocking fastener elements.
