摘要:
A device (10) to coat food products such as potato crisps and biscuits. The device (10) includes a flavour dispenser 21 that delivers granular flavour material to the products (12) being coated. The device (10) further includes a conveyor (11) with conveyor surfaces (15 to 18) that are arranged in cascade so that the food products tumble from one surface to the next so that the granular flavour material is applied to the various surfaces of the food products.

A machine 10 to aid in forming at least one flange 11 on tubular bag material 12. The machine 10 includes at least one assembly 28 provided with a longitudinally extending slot 22 through which a fold 13 passes to be heated by hot air delivered to the slot 22. A pair of pressure rollers 27 engage the heated fold 13 so that the bag material 12 of the fold 13 adheres to form the flange 11.
摘要:
A laser-sinterable powder product has been prepared having unique properties which allow the powder to be sintered in a selective laser sintering machine to form a sintered part which is near-fully dense. For most purposes, the sintered part is indistinguishable from another part having the same dimensions made by isotropically molding the powder. In addition to being freely flowable at a temperature near its softening temperature, a useful powder is disclosed that has a two-tier distribution in which substantially no primary particles have an average diameter greater than 180 .mu.m, provided further that the number average ratio of particles smaller than 53 .mu.m is greater than 80%, the remaining larger particles being in the size range from 53 .mu.m to 180 .mu.m. A powder with slow recrystallization rates, as evidenced by non-overlapping endothermic and exothermic peaks in their differential scanning calorimetry characteristics for scan rates of on the order of 10.degree. C. to 20.degree. C. per minute, will also result in sintered parts that are near-fully dense, with minimal dimensional distortion.

摘要:
A slip conveyor assembly 10. The assembly 10 includes six slip conveyors 11 to 16 being arranged in series. Each of the conveyors 11 to 16 includes a tray 18 of “U” transverse cross-section. Each tray 18 is operated by a drive assembly 19 that horizontally reciprocates (oscillates) the associated tray 18 to cause product to advance along the assembly 10. Adjacent trays 18 may be displaced so that there is a gap between adjacent trays through which product may be delivered.
摘要:
A vacuum belt assembly (10) to drive tubular bag material (11) through a packaging machine. The assembly (10) includes three belts (19, 20, 21) with the belts (19, 20, 21) being driven by rollers (22). The belts (20, 21) have respectively lengths (28, 29) being located in planes inclined by an angle greater than 0° but less than 180°, preferably an obtuse angle.
摘要:
A machine 10 to test bags 11 to detect faulty bags 11a. The machine 10 includes a probe assembly 23 including a belt 27 which supports a plurality of probes 31. More particularly the bags 11 are engaged by probe portions 33, with displacement of the probe portions 33 providing data for a CPU controller 24 enabling the detection of faulty bags 11a. Faulty bags 11a are then ejected from the conveyor 13 by bag ejector 21.
