A method for the optical recognition of capsules for hot beverages machines comprises the steps of introducing a capsule in a machine, stimulating the capsule by an exciting optical signal emitted by a light source, reading a feedback optical signal by an optical reader, acquisition of the values of the frequency and/or the time frame of the feedback optical signal, determining the fulfillment of predetermined conditions on the values of the frequency and/or the time frame. On the basis of the step of evaluating there is then a step of blocking the normal operation of the machine or a step of pursuing the normal operation of the machine.

A coupling device for coupling a component to an article includes a first retaining member that retains the component, a second retaining member that retains the article, a movement system for moving the first retaining member and the second retaining member between a non-operating position where the component and the article are spaced apart from one another, and an operating position where the component and the article are in a coupling position, and a detection system for detecting the positioning of the component on the first retaining member. The detection system includes an image detector device for capturing at least one image of the component when the component is retained by the first retaining member, and a processing unit provided for analysing the image captured by the image detector device and verifying if the component is retained on the first retaining member in a predefined position.

In an apparatus and a packaging process of capsules with an opening closed by a laminar lid obtained by cutting a strip, the ability of transporting the laminar lids in several lines is introduced, reducing the overall dimensions. The apparatus includes: a cutting device with a mechanism defining a portion of the strip where the strip is tensioned in a respective cutting plane, and one or more punches obtaining the laminar lids from the strip; a carousel-like transfer device, having transfer members movable along a closed path, with gripping heads configured to receive respective laminar lids from the cutting device. The cutting plane is in a vertical position, and the mutual position of the cutting device and the transfer device defines a gripping spot of the closed path, the laminar lids being retained in the transfer members on a respective plane in a vertical position.

A container includes a receptacle and a cover. The receptacle includes a base and a sidewall. The base has an interior surface and a passageway in an interior area of the base. The passageway provides fluid communication from an interior of the receptacle to an exterior of the receptacle. The sidewall extends upward from the interior surface of the base. The cover is configured to sealingly engage with a top edge of the sidewall, and includes a cover opening. The container is configured to accept input fluid through the cover opening and to provide a corresponding outflow of fluid through the passageway. The passageway allows the outflow fluid to flow from the container while accommodating an outflow needle of a beverage brewer.

A coupling unit for coupling a component for a container includes a coupling equipment. The coupling equipment includes: a frame, a housing constrained to the frame, a gripping device rotatably constrained with respect to the frame and including a retaining element to selectively retain the component, and a coupling device constrained to the gripping device with respect to the frame, the coupling device including a coupling element to constrain a portion of the component to a coupling surface of the container at a coupling position. The gripping device and the coupling device can move along an arc with a curved trajectory to a removal position where the retaining element is oriented to receive at least one component to be retained, and to a coupling position where the retaining element and the coupling element bring an abutment surface of the container and a couplable portion of the component into contact.

Described is a method for making single-use capsules for beverages including the steps of: providing an upper flange having at least one hole; providing a support having at least one seat for housing a rigid cup-shaped body; inserting a rigid cup-shaped body in said housing seat, said rigid cup-shaped body having an inner space and an open upper opening; providing a piece of filter material above the upper flange; actuating a first step of feeding, by means of a pushing element, a central portion of said piece of filter material towards said hole, up to an intermediate position; upon reaching said intermediate position of the pushing element, performing a main locking of said piece of filter material relative to said upper flange and making a main cut of the piece of filter material along a predetermined main closed cutting line, extending substantially circularly about said central portion, to define a filter for infusion of beverages.
