摘要： The present invention relates to a heating device having at least a first heating element 102 for heating at least one protective sleeve 105, 602 arranged around at least a first uncoated optical fiber section 501, 603. Said sleeve 105, 602 being arranged to shrink when exposed to heat to form a protecting member tightly enclosing said uncoated optical fiber section 501, 603. The at least first heating element is flexible, and arranged to take at least a first open state and a second substantially closed state. Said first open state is suitable for inserting and removing said protecting sleeve and fiber into and out off said heating device. Said heating element, in said second state, substantially surrounds said sleeve to form an enclosure around said sleeve, so that said heating element radiates heat around substantially the complete circumference of said sleeve.

摘要： An optical fiber welding apparatus comprises two casing halves (33) which are rotatable about shafts (51). The casings have their movements coupled to each other by cooperating gear segments and prevent exterior dust particles from reaching the welding location and protects the operator from the welding arc and possible emissions therefrom. The casings (33) have such a shape and are so mounted that they enclose the interior of the apparatus in a space-saving way. On the frame (11) of the welding apparatus, to which the shafts (51) are attached, loose fiber retainers are placed on surfaces intended therefor which have a weak slope. In order to retain the optical fibers an elastic magnetic retainer mechanism (71) is provided in order to press inserted fibers against alignment grooves. The surfaces, which press against inserted fibers, can be elevated a little in the closed position of the casings by operating a button (99), which acts on a lever (91), whereby the final position of inserted fibers can be adjusted. Further, in the frame (11) cavities are arranged where separate camera units (29) are placed. To obtain a background illumination light emitting diodes (21) are arranged, the light of which is reflected towards the welding location by mirrors (35) attached to the inner side of the casings (33).
