The chute assembly includes a timing gate device including a plurality of timing gates that regulates the delivery of batches of product from the weigher to the former. The gates are driven between a first position at which they inhibit the delivery of batches of product to the former and a second position permitting the flow of batches of product to the former.

Abstract: A slip conveyor assembly (10) having a plurality of slip conveyors (11 to 16). Each slip conveyor (11 to 16) has a tray (18) providing a conveyor surface (20) along which product is delivered. The trays (18) are arrangeable and caused to reciprocate so that product may be conveyed in either longitudinal direction, with at least two of the trays being arrangeable to provide a gap (32) therebetween to provide for delivery of product from the conveyor assembly (10).

Abstract: A rotary packaging machine 10 having rotatably driven stripper bars 17 and 18 that strip tubular bag material 36 prior to sealing of the bags being formed. To further inhibit material being located between the sealing jaws there is provided tube closer bars 28 and 29. The bar 28 has a longitudinally extending projection 34 that is received within a longitudinally extending recess 35 of the bar 29. The tubular bag material 36 by engagement within the recess 35 by the projection 34 laterally projects the bag material 36 and three longitudinally spaced locations 54.

Abstract: 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.

Abstract: 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.

Abstract: A slip conveyor (10) having an elongated pan (11) along which articles are conveyed in a predetermined direction. The pan (11) is vertically and horizontally reciprocated by a drive assembly (22). The drive assembly (22) includes a cowl (25) that governs the operation of a motor (23), the control (25) being configured to operate the motor (23) so that the pan (11) does not have a downward acceleration greater than gravity so that product on the pan (11) remains in contact therewith.

Abstract: A conveyor assembly 18 that detects bags that leak. The assembly 18 includes a first conveyor 24 that operates in unison with a second conveyor 29. The conveyors 24 and 29 confine the bags in chambers, with the bags being engaged by pressure assemblies 50 so that the bags that leak are reduced in volume. The bags are engaged at a downstream position and at an upstream position by detection devices 44 that provide a signal indicative of the volume of each bag. These signals are compared to thereby identify bags that leak.

Abstract: A device (10) to coat food products such as potato crisps and biscuits.

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.

Abstract: A packaging machine former (10) having a base (11) upon which there is mounted a former member (12). Strip bag material passes over the member (12) to be arranged from a strip configuration to a tubular configuration into which product to be packaged is delivered. The base (11) and member (12) have passages through which a gas is delivered to be included with the product in the bags being formed.

Abstract: A conveyor (10) that delivers product to a plurality of transverse conveyors of chutes (11). The conveyor (10) includes conveyor segments (12) along which the product is conveyed. Product is removed from the conveyor (10) by the lateral displacement of an upstream end 15 or a downstream end 16 of adjacent conveyor segments (12).

Abstract: A weigher for a packaging machine has buckets that deliver product batches. Each bucket includes a pair of spaced side walls between which a bottom extends, and over which the product passes. A bottom wall has at least one trough to control the trajectory of the product leaving the bucket to minimize angular velocity of the product about the vertical axis of a chute. The chute has a substantially vertical axis and receives the batches of product from the weighing buckets. The chute has a side wall converging downwardly from an upper opening to a lower opening, and an internal surface over which the product passes.

Abstract: An assembly and method for forming bags (10) having a “block bottom” with external flanges (13). The method and apparatus includes forming folds (18) in a strip (17) and delivering the strip (17) to a former (30) so that the folds (18) engage the forming surface (33) to thereby locate the flanges (18) on the exterior of the tubular bag material (32).

Abstract: 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 ?m, provided further that the number average ratio of particles smaller than 53 ?m is greater than 80%, the remaining larger particles being in the size range from 53 ?m to 180 ?m. A powder with slow recrystallization rates, as evidenced by non-overlapping or slightly overlapping endothermic and exothermic peaks in their differential scanning calorimetry characteristics for scan rates of on the order of 10° C. to 20° C.
