An injection unit for a shaping machine includes an injection element suitable for introducing a plasticized material into a mold tool by a linear movement of the injection element. The injection element is coupled in linear motion-transmitting relationship to a bearing element, and at least two linear drives are adapted to exert a force on the injection element by the bearing element. The force can be transmitted by a transmission element from the at least two linear drives to the bearing element and thus to the injection element, and at least one clearance is arranged between the bearing element and the transmission element such that deformations of the bearing element are not transmitted to the transmission element or are transmitted to a reduced degree.

A plasticizing unit for a molding machine includes a plasticizing cylinder, and the plasticizing cylinder has a feed zone and a filling opening for material to be plasticized. The filling opening is arranged adjacent to the feeding zone, and a thermal separating device is arranged between the feed zone and the filling opening. An active tempering device for the filling opening is provided, and the active tempering device includes at least one tempering conduit and a tempering medium turbulently flowing through the tempering conduit during operation of the active tempering device.

An apparatus for needling a non-woven web. The apparatus comprises at least one needle beam. The needle beam, the lower side of which comprises a needle board having a plurality of needles, is held by a beam support, which is guided by means of a vertical drive for an oscillating movement in an upward and downward movement and is guided by means of a horizontal drive for an oscillating movement in a reciprocating movement. At least two driven eccentric shafts and several connecting rods, which are assigned to the eccentric shafts and the free ends of which are coupled to the beam support, are provided as the vertical drive. The horizontal drive comprises at least one horizontal link, one end of which is connected to the beam support and the opposite end of which is coupled to a gear kinematics, which comprises an eccentric drive. In order to achieve the simplest and most compact possible design of the horizontal drive, the gear kinematics is formed according to the invention by a rocker, one end of which is held on a machine frame by means of a frame swivel joint and the opposite end of which comprises a double swivel joint, said rocker being coupled at the double swivel joint to the horizontal link and the eccentric drive.

Apparatus for needling a non-woven web

An apparatus is described for needling a non-woven material with a support ( ) for at least one needleboard ( ) with at least two eccentric drives ( ) which are drivably connected with the support ( ) via connecting rods ( ) and with a device for adjusting the mutual angular position of the two eccentric drives ( ). In order to provide advantageous constructional conditions it is proposed that the device for adjusting the mutual angular position of the two eccentric drives ( ) consists of a superposition gear ( ) in a gear train ( ) for the drive connection of the two eccentric drives ( ).

Apparatus for needling a non-woven material

An apparatus is described for needling a non-woven material with a support ( ) receiving at least one needleboard ( ), which support is drivable in a reciprocating fashion both in the needle-penetration direction ( ) as well as the direction of passage ( ) of the non-woven material and on which are coupled the connecting rods ( ) of two oppositely drivable eccentric drives ( ) for the drive in the needle-penetration direction ( ) and on which acts at least one additional eccentric drive ( ), and with a device for setting the movement component of the support in the direction of passage ( ) of the non-woven material. In order to provide advantageous constructional conditions it is proposed that the connecting rods ( ) of the two oppositely drivable eccentric drives ( ) extend inclined in an opposite direction with respect to the needle-penetration direction ( ), that the additional eccentric drive ( or ) revolves synchronously with one of the two other eccentric drives ( ), that the connecting rod ( or ) of the additional eccentric drive ( or ) which is also articulated on the support ( ) forms a parallelogram of links with the connecting rod ( or ) of the synchronously revolving eccentric drive ( or ) for the purpose of guiding the support ( ) and that the oppositely drivable eccentric drives ( ) are drivable through separate motors ( ) which are adjustable with respect to their mutual rotational angle position through a control device ( ).

The description relates to a facility for needling of fleece with at least one needle board driven to and fro in stitching direction, which can be additionally driven in pendulum fashion in fleece feed direction ( ) by means of an eccentric drive, which is provided with a connecting rod ( ) articulated to a rocker arm ( ) and a connecting pitman ( ) to the needle board effective on this connecting rod assembly. To be able to easily adjust the rocking amplitude of the needle board in fleece feed direction ( ) it is suggested that the swivel bearing ( ) of the rocker arm ( ) is seated on a rotatable crank arm ( ) and that, for adjustment of the rocking amplitude of the connecting pitman ( ), the neutral rocking position of the rocker arm ( ) is adjustable via the crank arm ( ) between an end position essentially running in the direction of the connecting pitman ( ) and an end position running transverse thereto.
