Abstract: SUMMARY ABSTRACT            The invention relates to a sealing arrangement (1) for a moistening unit (F) on an offset printing machine with a moisture application roller (7) and a metering roller (6), which roll against one another in such a way that a groove (5) accommodating a reserve of moistening agent is formed with the upper gusset between the metering roller (6) and the application roller (7), with a seal retention (3), mountable on a lateral part (8) of the moistening unit (F), and a sealing element (2) accommodated in this seal retention, whereby the seal retention (3) is pre-stressed against the front face of the rollers, and whereby the sealing element (2) provides a seal supported radially on the metering roller (6) and adjoining the moisture application roller (7) on the front face.  In order to permit a secure sealing of the groove accommodating the reserve of moistening agent, and at the same time to permit an operationally easy exchange of the sealing element, it is envisaged that the seal retention (3) leaves free a swivelling path (x) for the sealing element (2) into a position of readiness for removal, into Abstract which position the sealing element (2) can be swivelled by turning it around the metering roller (6).

Inventor: SAVICH PETER P
IPC: B29C49/04
Filed: 1991-10-23
Abstract: An in-mold label dispenser for a blow molding machine includes a dispensing head mounted on a base for movement along a first path from adjacent a label magazine to between the open sections of a mold and a label carrier mounted on the dispensing head for movement along a second path substantially transverse to the first path from a retracted to an extended position.  A drive mechanism is mounted in the base for moving the dispensing head along the first path and the label carrier along the second path in co-ordination with the opening of the mold.  The drive mechanism includes an elongated support extending between the base and the mold sections for supporting the dispensing head as it moves along the first path and means for oscillating the elongated support about an axis transverse to the second path.  A lever assembly is connected between the elongated support and the label carrier to provide movement of the label carrier along the second path for receiving a label at the label magazine and depositing it within the mold cavity.  An adjustable stop assembly is provided on the label carrier for stopping movement of the label carrier along the second path after the label carrier has moved a sufficient distance into the mold section to establish a gap of predetermined width between the label and the wall of the mold cavity.  The lever assembly includes a bias means which is so arranged as to permit continued movement of the oscillating support after the stop assembly has been engaged to stop movement of the label carrier, thereby preventing damage to the label carrier.
