A method for forming pieces of food dough and an apparatus thereof is able to cut the food dough continuously extruded through a nozzle along the shape of the hole of the nozzle without causing deformation, and to locate pieces of the food dough on a conveyor without causing deformation. The apparatus for forming pieces of food dough comprises an extruding device and a cutting device, wherein the extruding device comprises a nozzle to continuously extrude food dough downward, and the cutting device comprises a cutting blade to cut the food dough into the pieces of food dough, a moving mechanism to move the cutting blade forward from an initial position, then to move the cutting blade downward, and then to return the cutting blade to the initial position, and a carrying-out conveyor, which is disposed below the nozzle and moves in the direction that the cutting blade moves forward.

A method for automatically cutting off a material passage part while reducing manufacturing cost and cycle time. This method includes preparing a cutting device capable of moving in an automatic control coordinate system, placing the molded article without fixing the molded article, detecting a shape of the molded article by a sensor, acquiring a position of the material passage part in the coordinate system, determining a position of a cut spot in the material passage part as a target position in the coordinate system, moving the cutting device in the coordinate system and disposing the cutting device on a work position for cutting the cut spot, and cutting the cut spot by the cutting device arranged on the work position.

A device includes a blade, which is movable within an associated working space for cutting product units, and a conveying device in which the product units can be individually conveyed into the working space of the blade. The conveying device includes at least one two-part conveying channel associated with the blade, in which on one side first conveyor elements and on the other side second conveyor elements are guided, which are assigned to one another in pairs and which have each a recess for partially receiving a separated product unit. The sides of the first and second conveyor elements, which are facing one another, delimit therebetween the free working space, so that the blade is guidable within the working space partially or completely through the product units held in the first and second conveyor elements which correspond to one another.

A cutting device, knife carrier suitable for use in the cutting device, a cutting system and method for cutting a strand of stacked bands of a food product are disclosed. The cutting device, knife carrier, cutting system and method combine a transverse cutting knife with a diagonal cutting knife disposed at an oblique angle with respect to the transverse cutting knife. The diagonal cutting knife diagonally cuts the stack simultaneously with transverse cutting of the stack by the transverse cutting knife to form substantially triangular prism shaped stacks made of corresponding substantially triangular shaped slices. A food product obtainable by the method is disclosed, wherein (a) the food product comprises at least two stacks of food product, wherein the edges of individual slices forming the hypotenuse of one substantially triangular prism shaped stack are disposed adjacent to the edges of the individual slices forming the hypotenuse of the other substantially triangular prism shaped stack in one-to-one relation to one another and/or (b) the substantially triangular footprint of each stack is in the form of a quadrilateral, wherein at least 80 percent of the surface area of the quadrilateral is triangular.

An apparatus for cutting pipes made of thermoplastic material, including: a tool for cutting pipes, an arm for supporting the tool which is movable between a non-operating configuration wherein the tool is disengaged from the pipe and an operating configuration wherein the tool is engaged in the pipe to exert a cutting action on the pipe, a lever which can be constrained to the arm, supporting device configured to move said lever, a locking unit for reversibly constraining said arm and said lever and disengaging means to move said arm from the operating configuration to the non-operating configuration.

Apparatus for producing tubular products starting from a tubular body, wherein the apparatus comprises a cutting unit (10) disposed along a directrix of feed (A) of the tubular body to be cut, in order to obtain the tubular products. The cutting unit (10) comprises a rotating arm (11) mounted rotating around a first axis of rotation (R1), and at least one cutting member (12) mounted rotatable on the arm (11) in such a way as to rotate around a second axis of rotation (R2). The cutting member (12) is able to be moved toward a cutting position, in which the cutting member (12) interacts with the tubular body in order to cut it.

In a plastic strand granulator the width of a cutting gap between a cutting rotor and a knife strip is gauged by an adjustment mechanism by setting the position of the knife strip. For this purpose the adjustment mechanism has an actuator with a differential thread having a reducing transmission ratio. The adjustment mechanism can advantageously be gauged automatically to a predetermined cutting gap width by a control circuit, wherein the adjustment mechanism is gauged in dependence on vibration parameters which are captured on the knife strip or on the cutting rotor. For this purpose, ultrasonic vibrations are introduced into the component in question and detected at some distance therefrom and evaluated.
