A tool for pressing a foamed material onto a substrate, a manufacturing apparatus thereof, and a method for manufacturing a laminated structure of a heat-retaining container are disclosed. The tool comprises a body, a blade portion extending in a lengthwise direction from the body, and a press portion extending in the lengthwise direction from the body and configured for pressing the foamed material onto the substrate. The tool may be used to press a foamed material sheet onto a paper substrate and form a tear line on the foamed material sheet at the same time to simplify the manufacturing process of the laminated structure of a heat-retaining container.

A cutting tool for cutting netting used for encasing meat products comprises a blade and a guard. A control circuit is electrically connected to the blade, and configured to maintain the temperature of the blade at a cutting temperature in the range of 300° C. to 500° C. The guard defines an interior cavity surrounding the blade and further comprises a slot exposing a portion of the blade. The guarding is further shaped to define a funnel at a distal end of the cutting tool leading to the slot such that in use the funnel guides a netting to be cut towards the blade. The cutting tool may be provided as a hand tool or in a bench mounted form.

This application relates to an amplifier selectively operable in first or second modes. The first mode is a BTL mode with first and second output drivers (103p, 103n) both active to generate respective driving signals that vary with an input signal. The second mode is an SE mode, where the first output driver (103p) is active to generate a driving signal at and the output of the second driver (103n) is held constant. A controller (201) selectively controls the mode based on an indication of output signal amplitude. In the first mode, a ratio of magnitude of the two driving signals varies with the indication of output signal amplitude, i.e. the magnitudes of the two driving signals may vary so as to be not equal.
