Abstract: An apparatus for forming shaped material from a raw material employs a substantially cylindrical housing 3 with a screw shaft 2 arranged in it. A frontal end surface of the housing, located at the downstream end is closed by a counter-pressure member 9 which, together with the housing 3, limits a discharge opening. The counter-pressure member is held against conveyed material by a force of predetermined magnitude acting opposite the conveying direction. Surprisingly, this results in a high compactness and a good stability of shape of the shaped material, and also facilitates a starting of such an apparatus. Removable teeth define an orifice.

Abstract: An apparatus for spinning bicomponent sheath/core filaments having a distributor plate and spinnerette and a shim positioned between the distributor plate and spinnerette to effect a controlled pressure drop of the sheath polymer material. In particular, the distributor plate and spinnerette each have a plurality of spaced core polymer flow passages and sheath polymer passages wherein the respective core polymer flow passages are axially aligned and the respective sheath polymer flow passages are aligned. The shim is positioned between the spinnerette and distributor plate to control the sheath polymer flow from the outlet of the distributor sheath polymer flow passages to the inlet of each spinnerette core polymer flow passage separately. Producing sheath/core bicomponent fibers using this apparatus results in fibers having concentric sheath/core configurations and increased throughput.

Abstract: In a weighing and labelling system for a product, a suction unit (35) having its lower surface carrying a label (Z) is lowered by a drive motor (25) and, immediately before the suction unit (35) is brought into contact with a product (Y) to be wrapped, the supply of an electric power to the drive motor (25) is interrupted to allow the label (Z) to be applied to the product (Y) by the effect of an inertia operation and, thereafter, the suction unit (35) is immediately elevated. Alternatively, by the utilization of a servo mechanism, the label (Z) is applied.

Abstract: An apparatus for applying heat sensitive labels and pressure sensitive labels wherein the apparatus can be readily changed to apply heat sensitive labels or pressure sensitive labels from a web along which the labels are positioned. In one mode for applying heat sensitive labels, the web is moved from a feed reel adjacent a preheater and a platen where successive labels are peeled from the web and applied to successive containers on a turret and thereafter the web is stored on a take-up reel. In a second mode, the preheater and platen are removed, a peel bar assembly is positioned in place of the platen, and the web with the labels thereon is moved about the peel bar assembly to peel a label from the web and apply the pressure sensitive label to an article on the turret and the web is thereafter redirected to the take-up reel.
