摘要:
A labeler for labeling plastic containers in the blow mold in a rotary blow molder, with a blow wheel having arranged thereon a plurality of blow molds with a lowerable blow mold bottom, and at least one label dispenser used for providing tubular labels. The blow mold bottom is implemented such that a label can be introduced via the blow mold bottom into the blow mold before the blowing process takes place, which facilitates a spatial separation of the label supply from the feeder star wheel of the blow wheel and allows a substantially simultaneous insertion of the label and of the preform.
摘要:
A labeler for in-mold labeling of plastic bottles as well as to a labeling method for use of the labeler, including that a transfer star wheel and a transfer device of the labeler move the preforms and the labels in a transfer region towards one another in such a way that a respective label is only affixed to a circumferential subarea of a perform. In this manner, the label can be inserted in the blow mold in a particularly fast and reliable manner and excessive stretching of the label during blow molding can be avoided.

A chuck for receiving a working tool (2) rotable about a longitudinal axis (A) includes a receiving sleeve (3) having a guide surface (12) extending along the longitudinal axis (A) and at least three, axially extending, up to a free end surface (4) of the chuck (1), entraining grooves (5) located in front of the guide surface (12), arranged radially outside of the radial dimension (R) at angles of 0°, 120°, and 240°, and each having a central angle (α) defined with respect to the radial dimension (R) and amounting to at least 40°; and at least one locking member (6) radially displaceable over the radial dimension (R) and arranged between two circumferentially adjacent entraining grooves (5) and diametrically opposite a third entraining groove (5).

A drill in particular for a hammer drill for drilling in stone, concrete and the like includes a drilling head (2) formed as a hard material body with radial legs (18,19) and having at least three radially extending cutting bits (5) formed on the radial legs (18,19), and a centering tip (11;21) provided in a center of the hard material body and projecting beyond one of the cutting bits (16,17), with the centering tip (11;21) having concave limiting surfaces (12;22) stretching between the linearly extending auxiliary cutting edges (13;24,24).

A chuck includes a hollow cylindrical sleeve (3) having at least two, opposite, rotation transmitting strip-shaped webs (4a, 4b) projecting radially inward, and at least one locking member (2) radially displaceable through a radial opening formed in the receiving sleeve, with the receiving side end of the rotation transmitting webs (4a, 4b) being spaced from a receiving side edge of the radial opening (6) by a distance (X) 1.5 times greater than the guide diameter (D) of the receiving sleeve (3).

A shank of a rotary-percussion working tool (2) has at least two, diametrically opposite locking grooves (5a, 5b) each having a locking shoulder (11) at an axial locking end (3) and spaced from a free end surface (4) of the shank (1), and an end shoulder (12) axially spaced from the locking shoulder (11) in a direction of a working tool-side end of the shank (1) and spaced from the axial locking end (3) of the shank (1) by a length (L) amounting at least to three times of a guide diameter (D) of the shank (1), and at least two entraining grooves (6a, 6b) mutually tangentially offset with respect to the locking grooves (5a, 5b), opening toward the free end surface (4), and having a tangential groove width (B) and at least one tangential, force application surface (7) extending over a contact length (K).
摘要:
A drill, which is used in a hammer drill for drilling holes in stone, concrete and the like, includes a drilling head (10, 20, 30) formed of a hard material and provided, at its first end (5) with at least one main bit (3) having a tip (4), and at a second end (6) located opposite the first end (5), with a bottom surface (7) for the mounting the drilling head (10; 20; 30) on the drill stem (8), and having a plurality of axially extending through-grooves (11; 21; 31) for removing drillings produced during a drilling process and having a cross-section which increases, at least regionwise, in a direction toward the bottom surface (7) of the drilling head (10; 20; 30).
摘要:
A chuck for receiving a working tool driven by a power tool includes a hollow cylindrical sleeve (4) for receiving the working tool (2), strip-shaped, rotation-transmitting webs (5a, 5b) projecting radially inward from the receiving sleeve (4), at least one radially displaceable locking member (7a); at least two guide members (9a, 9b) provided in a working tool-side guide region (F) of the guide diameter (D) of the receiving sleeve and spaced from the rotation-transmitting webs (5a, 5b), and a manually rotatable clamping sleeve (8a) for displacing the guide members (9a, 9b) radially inwardly.
