The invention relates to an electromagnetic drive for a cutting device of a textile machine for severing a thread, to a cutting device having an electromagnetic drive, and to a yarn clearer having a cutting device. In order to provide an electromagnetic drive for a cutting device of a textile machine for severing a thread, the electromagnetic drive enabling particularly efficient, fast and/or precise operation of a cutting device having a cutting blade with large cutting force and also preferably enabling a particularly long uninterrupted and maintenance-free operating time, it is provided that: —the piston is partly guided in a core tube contained by the solenoid, the core tube being formed by the component which is stationary relative to the piston, and the axial air gap extending between the end face of the piston and an end face of the core tube, which end face is formed by the counter face; and/or—the piston is at least partly hollow; and/or—the piston is operatively connected to a returning element for returning the piston after the piston has been moved out of the rest position, the returning element having a progressive and, in particular, non-linear spring characteristic curve; and/or—the piston is surrounded by a solenoid core, which is stationary relative to the piston and which either is produced by powder injection moulding and/or is made from a soft ferrite or is made from a plurality of layers of an electrical steel sheet, more particularly from a non-grain-oriented electrical steel sheet.

The cutting unit includes an upper positioning seat coupled co-movably to the first drive chain, a lower positioning seat coupled co-movably to the second drive chain, and at least one cutting blade secured between the upper and lower positioning seats.

A device (1) for cutting food comprises a cutting unit (10) having a rotatable carrier (20), a slicing knife (21) associated with the carrier (20) at one side of the carrier (20) for slicing the food, and at least one dicing knife associated with the carrier (20) at another side of the carrier (20) for dicing the food. The cutting unit (10) furthermore comprises a protection element (30) which is designed to be arranged vis-à-vis a side of the carrier (20) where the dicing knife associated with the carrier (20) is present, for delimiting a dicing space for the dicing knife associated with the carrier (20) to move through during operation, wherein the protection element (30) is equipped with at least one annular groove (33) at a side for facing the carrier (20), for receiving a free end of the dicing knife associated with the carrier (20).

A slicing machine for slicing meat strands that have a cross section that varies over a longitudinal extension in large numbers and as quickly as possible into weight precise slices. In one embodiment, two meat strands are received adjacent to each other in a respective form tube and pushed against a respective separately adjustable stop plate independently from each other by a controlled longitudinal press plunger and compressed in the longitudinal direction. In addition, a cross section of the form tubes may be reduced in a first transversal direction jointly and in a second transversal direction independently from each other and thus the respective meat strand is transversally compressed to a constant cross section prior to slicing.

A machine is shown having a winding unit (3) and a cutting unit (7) to cut a tube (T) being formed around a mandrel (5). The cutting unit (7) has a rotating cutting blade (9) provided with motion along a circular trajectory, defined by means of a system of cross guides and a fastening to a center of a circular trajectory. The position of the center (33B) of the circular trajectory of the rotating cutting blade (9) is changed according to the direction of movement of the blade with respect to the mandrel, so that the rotating cutting blade (9) cuts the tube (T) during a forward movement and is released form the tube during a backward movement. Methods for production of tubes by means of helical winding of one or more strips of web material around a mandrel are shown as well.

A hand-held cutting device configured to safely, easily, and reliably remove the plastic tip of the plastic packaging of a Freeze Pop is disclosed. The device includes a housing with a slot into which the tip of the unopened Freeze Pop is inserted. Inside the slot is an internal cutting mechanism which produces a curved cut to remove the tip of the Freeze Pop. The tip then falls into a collection chamber which may be opened for easy disposal of plastic scraps. The entire device is storable on a magnetic surface via a removable magnetic component.

This invention provides web-cutting mechanism that can be mounted in line at an appropriate location between the web-handling peripheral (printer) and a web roll. The cutting mechanism operates before the available storage in the winder festoon has been exhausted, and decouples the roll's energy from the web. The cutting mechanism can employ a blade that is drawn through the web solely by the movement of the web itself. The blade is mounted at a (e.g.) 45-degree angle to web travel, causing it to be pulled through the web. A negator spring assembly and associated cable drives the blade into the side edge of the web when a slide-mounted blade shuttle assembly is released by a latching pawl of a solenoid assembly. The solenoid is triggered by a signal indicating an emergency stop condition, such as an upstream jam.

A cutting device for cutting an optical fiber running in a first direction includes a supporting piece having a free end and a fixed end and having resilience, a cutting blade supported by the supporting piece that comes into contact with the optical fiber to make a right angle with the optical fiber at a point of the contact, and a driving device. The driving device is configured to press the supporting piece in a second direction in a plane perpendicular to the first direction, with the second direction not intersecting with the first direction.

A device (I) for moving a treatment head (JO) and a tray (20) in relation to a plane P., The tray (20) of any shape is inscribed within a rectangle of width A and length 0.8., and includes a first driver (21) suitable for cooperating with a first actuator (22) so as to move the tray (20) in translation within a plane that is parallel to said plane .P. in a movement zone (30) formed from at least two perpendicular edges associated with a reference frame, Q, y, in a direction that is normally parallel to one of said axes or y, the device.
