Abstract: An apparatus for forming a tube (54) of pocket material (22) for manufacturing a pocket spring string includes a cartridge (30) for guiding the pocket material (22). The cartridge (30) has at least one first element (61) and at least one second element (62). A relative position between the at least one first element (61) and the at least one second element (62) may be set in a direction (60) perpendicular to an axis (50) of the cartridge (30), in order to adjust a spacing between sides of the cartridge (30).

Abstract: A premix burner has a mixing section (3) for a heat generator, sectional conical shells (5) which complement one another to form a swirl body, enclose a conically widening swirl space (6), and mutually define tangential air-inlet slots (7), along which feeds (8) for gaseous fuel are provided in a distributed manner, having at least one fuel feed (11) for liquid fuel, this fuel feed (11) being arranged along a burner axis (A) passing centrally through the swirl space (6), and having a mixing tube (4) adjoining the swirl body downstream via a transition piece (2). At least one additional fuel feed (13) for liquid fuel is provided in the region of the swirl body, the transition piece (2), and/or the mixing tube (4).

Abstract: A premix burner for a heat generator has partial cone shells (5) which make up a vortex generator, and which encompass a conically widening vortex chamber (6) and mutually define tangential air inlet slots (7), and also with feeds for gaseous and/or liquid fuel, of which at least one is arranged along the air inlet slots (7) on the partial cone shells (5), and at least one other is arranged along a burner axis (A) which centrally passes through the vortex chamber (6). At least n partial cone shells (5) encompass the vortex chamber (6), and define n air inlet slots (7), with n?3, preferably n?5, the n air inlet slots (7) each have at least a maximum slot width (10) which is equal to or larger than that slot width (10) which a generic type premix burner (1) of the same size and dimensioning with m?2 partial cone shells (5) and m air inlet slots (7) has.

Abstract: A servo drive spring conveyance apparatus is disclosed in which a spring is grasped by a grabbing jaw of a multi-armed conveying star and fed from there to additional stations. The conveyance apparatus includes two belt loops that are provided for the conveyance of the springs.

Abstract: Device for transferring springs to an assembly machine, wherein the sprints to be transferred are retained in a guide device wherein for the transfer of the springs sliders are provided engaging at the end winds of the springs.

Abstract: Described is an electronically regulated coiling apparatus for mattress and upholstery springs comprising essentially a wire draw-in, a wire guidance, a cutting device and a bending device for a wire to be processed, and due to short drive trains equipped with few transfer elements, in particular for the bending device, improved torsional rigidity and flexural strength of the particular drive train is attained. The electronically regulated servomotors used according to the invention can therefore transfer their movement directly onto the bending tools and the drive rollers by interconnecting few transfer elements. This permits bending a wire with decreased tolerances into a corresponding spring.
