In a belling machine and in a method of forming a socket at the heated end of a pipe, an end of a pipe made of thermoplastic material on which a socket is to be formed is heated until it is in a deformable state, inserted in a forming chamber and formed into a socket shape. Process air, taken from a compressed air source, is conveyed into an evaporator of a refrigerating machine using a refrigerant recirculating in a closed circuit and passes through the evaporator, resulting in transfer of heat from the process air to the refrigerant inside the evaporator. The process air is then conveyed to the forming chamber through an inlet, at least to cool the material of the end of the pipe at least by means of a process air flow inside the forming chamber.

The invention relates to use of polylactide (PLA) as an extruded polymer coating on paper or board intended for the production of containers and packages, which are heated in a stove or microwave oven. According to the invention a polyfunctional cross-linking agent, such as trialkyl isocyanureate (TAIC), is blended with PLA, and the extruded coating layer is subjected to cross-linking electron beam (EB) radiation. PLA may be used as such or blended with another biodegradable polyester such as polybutylene succinate (PBS). EB radiation has been found to improve adhesion of the coating to the paper or board substrate, heat-scalability of the coating, and heat-resistance of the finished containers and packages.

The cap has a shell made of a synthetic resin formed in a generally hemispherical, hollow shape, and a recess defined by an inner surface of the shell in a generally hemispherical shape. The method includes filling the recess with a fluid sealant, which contains a mixture of a thermosetting substance and a curing agent that is freezable prior to curing, such that while the sealant is frozen, no curing takes place, and when the sealant is subsequently heated and thawed, its original fluidity is restored and curing of the thermosetting substance restarts. The sealant is then frozen while the sealant is filled in the cap. Subsequently the sealant is thawed and any condensation that forms on the sealant or the cap during the thawing is removed by drying.

A method of finding a target conveying capacity of a pumping includes a temperature-control flow through a temperature-control channel carried out according to a control variable by using a throttle as an actuating element such that a temperature-control volume flow remains substantially constant. A conveying flow of the pumping system is measured, and a pump starting from a starting conveying capacity independent of the control of the temperature-control volume flow is driven such that a conveying capacity of the pumping system is reduced to a reduced conveying capacity. Then, a check is made to find whether the conveying flow remains substantially constant and, if this is the case, the reduced conveying capacity is determined to be the target conveying capacity or. If this is not the case despite the control of the temperature-control volume flow, the starting conveying capacity is determined to be the target conveying capacity.
