<p>#CMT# #/CMT# The method involves forming two axial offset blind bores with a flat base. Smooth pins (5) are chosen and introduced in the bores, after mounting inner elements (4) of a strap e.g. rigid/articulated metal strap (1), on the pins. The pins and the elements are welded by carrying out electron beam bombardment on upper/lower wall of outer elements (2, 3). A termination operation is performed on the bombarded wall to remove a welding seam. The bore formation, pin choosing and introduction, pin and outer element welding and operation performance are carried out to fix the pins on the outer elements. #CMT#USE : #/CMT# Method for assembling a strap e.g. rigid/articulated metal strap such as wrist-watch strap (all claimed). #CMT#ADVANTAGE : #/CMT# The method permits to assemble the strap, in an inexpensive manner. The flat base of the offset blind bores permits elimination or reduction of air pocket that is subsisted at the base of the bores, if ends of the pins are not contacted with the flat base of the bores, in a simple manner, thus improving quality of welding of the pins and the outer elements of the strap. The method permits the strap to be easily adapted to hands of a user. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a partial view of a metal strap with three rows of elements. 1 : Rigid or articulated metal strap 2, 3 : Outer elements 4 : Inner elements 5 : Smooth pins #CMT#METALLURGY : #/CMT# The outer and inner elements and the pins of the strap are made of steel, gold and titanium.</p> |
