A cutting device includes a tool drive, cutting tool having first and second connecting parts respectively connected to first and second followers, and a guiding device, that includes a first guiding unit with first and second guiding modules. The first guiding module includes guiding wheels, which are held each by related bearing devices rotatable in a guiding plane, peripherally adjacent to each other at a first transfer position. The guiding wheels include an outwardly open receiving opening suitable for receiving the first follower, rotatable by the tool drive in opposite directions with the same angular velocity. The guiding wheels are arranged so that their receiving openings lie opposite one another at the first transfer position after each revolution, so that the first follower is transferable alternately from one receiving opening into the other at the first transfer position and is guidable alternately along the periphery of the a guiding wheel.

The invention relates to an apparatus for comminuting solids into pieces, in particular solid foodstuffs into foodstuff pieces, which has a container at the first end cross-sectional opening of which at least one knife is arranged, the first cross-sectional opening forming an inlet opening or being covered by a first lid, which has an inlet opening, the container being driven in a reciprocating motion parallel to or at an angle to the plane in which the first cross-sectional opening extends, with a feed chute, the outlet opening of which is arranged in the region of the first cross-sectional opening and the opposite inlet opening of which is spaced from its outlet opening.

A heat chamfering apparatus includes a heated body configured to peel an edge of a glass panel by applying thermal shock to the glass panel while being in contact with the edge of the glass panel and a heater heating the heated body. The heated body includes a heated region and a contact region in a longitudinal direction thereof, the heated region being heated by the heater, and the contact region being configured to be in contact with the glass panel. The cross-sectional area of the contact region is smaller than the cross-sectional area of the contact region. A heat chamfering method includes peeling an edge of a glass panel by applying thermal shock to the edge of the glass panel by moving a heated body heated by a heater relatively with respect to the glass panel along and in contact with the edge of the glass panel.

A heat chamfering apparatus. A support unit supports a glass panel. A heat chamfering unit heat-chamfers an edge of the glass panel by applying thermal shock thereto. The support unit includes a contact support portion supporting the glass panel while in contact with the glass panel and a base portion configured to support the contact support portion. The contact support portion is formed from a first material. The base portion is formed from a second material. The first material has a smaller change in temperature due to lower thermal conductivity and a smaller change in size at high temperature due to a smaller coefficient of thermal expansion while being more ductile due to lower hardness, compared to the second material. In a heat chamfering method, a glass panel is located on a support unit, and an edge of the glass panel is heat-chamfered by applying thermal shock thereto.
