Abstract: A cartonizing machine wherein articles are arranged either individually or in groups in trays passing through a feeding station and to and through a loading station wherein the articles on the successive trays are pushed transversely into respective carton members conveyed with a mutual spacing. The filling of the trays is facilitated when the trays are closely juxtaposed with such being achieved by a tray conveyor system disposed so as to operate with a reduced tray pitch and a tray speed in the feeding station.

Abstract: A method and system for producing extruded edible ice products wherein an extruded string is conveyed unbroken through a continuous freezing zone, with only constrictions or notches being provided in the string by transversely movable tools while the ice substance is still formable. After a hard freezing of the extruded string, single bodies are separated from the extruded string by a simple successive breaking action on a front end of the string, and a desired distance between individual severed bodies can be produced by permitting the bodies to fall onto a conveyor moving at a speed which is higher than a conveying speed of the extruded string.

Abstract: It has been recognized long ago that stickless frozen block bodies of a size corresponding to the ice block bodies of ordinary ice lollies may be produced with the aid of standard freezing machines for producing the ice lollies, when these machines are modified such that the individual sticks are replaced by pin members on an uptake device as operable to lift a whole row of ice bodies up from their freezing pocket members, whereafter the ice bodies are caused to be retracted from the pins. However, the correct and automatic mounting of the uptake device relative the freezing pockets is very problematic, and the invention provides for the improvement that use is made of individual sticks for the single freezing pockets, whereby these sticks, prior to their final retraction from the ice bodies, may be handled automatically with the use of both mounting and retraction means, which are already highly developed for the production of ice lollies.

Abstract: Frozen confection articles are produced in non-enveloped, openable moulds by subjecting the closed moulds to an innoxious freezing medium such as very cold air. An apparatus for producing such frozen or moulded articles comprises a plurality of parallel, endless rows of moulds moving along a closed path of straightlined and curved configurations, these moulds each consisting of opposed, mutually hinged mould parts, which are forced together during motion along the straightlined parts of said path, as corresponding to setting or freezing zones, while the moulds are openable for discharging of the hardened or frozen products as they are guided along the curved path, in which the moulds diverge from each other and thus provide space for the opening thereof.

Abstract: From a row of objects which are conveyed on an intermittently movable feeding conveyor, every second object is deposited on lines of wrapping materials at a first station, which lines are advanced continuously under the feeding conveyor, and the remaining objects are deposited on the same lines of wrapping materials at a following station. In connection with one or both depositing steps. the objects are shifted transversely of the direction in which said lines are advanced. Thus, the number of lines of wrapping material is only half the number of objects in each row, whereas the distance between the lines will be increased so much that the lines may be sealed lengthwise and crosswise by means of rotating sealing means.

Abstract: A system for dispensing a viscid medium from a supply medium flow to a number of receptacles, with the system including a filling station and a distributor having an inlet for a pressurized supply medium flow and a number of outlets individually connected to a series of dispenser openings located in the filling station. A support is provided for sequentially moving consecutive groups of receptacles through the filling station to align a single receptacle of each group with the respective dispenser openings. An outlet valve arrangement is located in a path of the medium flow upstream of the dispenser openings. A valve control is operable to repeatingly open and close the outlet valve arrangement to allow concurrent medium outlet from the dispenser openings during an opening time interval corresponding to a predetermined medium volume being dispensed for a required filling of the receptacles of the respective consecutive groups.

Abstract: Ice cream lollies of complex shapes are produced by a die pressing operation, whereby a prefrozen and deformable lolly body is placed between a pair of die tools. The bodies to be die shaped may be either conventionally produced bodies as prefrozen about a stick, in which the body is held during the shaping operation, or they may be lumps of extruded prefrozen material, whereby a preparatory conventional mold freezing can be avoided. The die tools may be used additionally for concurrently providing and sealing an envelope about the final product, thus finishing it as a sales product.

Abstract: Apparatus for receiving frozen confections supplied in a single row on a supply conveyor and delivering the confections to a discharge conveyor located at a lower level. The supply conveyor overlaps a rotary turret and a movable stop provided above the turret halts every second confection arriving on the supply conveyor following which a carrier on a movable chain pushes the confections along a transverse chute down onto the discharge conveyor. The remaining confections are allowed to travel through 180.degree. on the turret following which they are halted by a stationary stop. Carriers on a second movable chain then push each of the latter confections along a second transverse chute onto the discharge conveyor in a space between two confections delivered via the first chute and with reversed orientation. The discharge conveyor, the carrier chains and the turret move continuously and in synchronism.

Abstract: To mix a gas with a mass flowing continuously through a conduit, the gas is caused to flow from a pressurized gas supply into the conduit by way of a nozzle in which the gas expands at a critical pressure ratio; and the pressure of the gas flowing from the nozzle is increased before the gas is introduced into the flowing mass.

Abstract: A method and an apparatus for determining the relative air or gas content in a product flowing through a conduit. By means of two substantially synchronized pistons moving in opposed cylinders, a sample of the product is transferred from the conduit to a sampling chamber defined in one of the cylinders between the pistons. After the sample has been isolated from the material flowing through the conduit, the pistons are moved towards one another whereby the volume of the sampling chamber is reduced to a predetermined value. The compression of the sample results in an increased pressure, and when the pressure has reached a predetermined value, an overflow valve is opened to let excess material flow from the sampling chamber back to the conduit. When the movement of the pistons towards one another has stopped and said predetermined pressure has been established in the sample, a predetermined expansion of the sample is effected by moving the pistons a predetermined distance from one another.
